The critical numbers of the function on the interval 0 ≤ θ < 2π are:

θ = 0, θ = π, θ = π/3, θ = 2π/3, θ = 4π/3, and θ = 5π/3.

we now have the smaller values of θ are θ = 0 and θ = π/3, while the larger values are θ = 2

The critical numbers of a function are described as the values of the independent variable for which the function is not differentiable.

In our own case, the function f(θ) = 2cos(θ) +(sin(θ))^2, the critical numbers are the values of θ for which the derivative is not defined.

We can write the derivative of the function as:

f'(θ) = -2sin(θ) + 2sin(θ)cos(θ) = sin(θ)(2cos(θ) - 1)

The derivative is not defined when sin(θ) = 0 or cos(θ) = 1/2.

The values of θ for which sin(θ) = 0 are θ = 0, θ = π, θ = 2π, etc.

The values of θ for which cos(θ) = 1/2 are θ = π/3, θ = 2π/3, θ = 4π/3, θ = 5π/3, etc.

Hence, the critical numbers of the function on the interval 0 ≤ θ < 2π are:

θ = 0, θ = π, θ = π/3, θ = 2π/3, θ = 4π/3, and θ = 5π/3.

The weight that separates the bottom 5% is approximately 5.02 ounces.

To find the weights that separate the top 5% and the bottom 5%, we need to use the z-score formula and the standard normal distribution table.

First, let's find the z-score for the top 5%. Using the standard normal distribution table, we find that the z-score for the top 5% is approximately 1.645.

Next, we can use the formula z = (x - μ) / σ, where z is the z-score, x is the weight we're trying to find, μ is the mean, and σ is the standard deviation.

For the top 5%, we have:

1.645 = (x - 5.12) / 0.07

Solving for x, we get:

x = 5.12 + 1.645 * 0.07

x ≈ 5.22 ounces

Therefore, the weight that separates the top 5% is approximately 5.22 ounces.

To find the weight that separates the bottom 5%, we use the same process but with a negative z-score. The z-score for the bottom 5% is approximately -1.645.

-1.645 = (x - 5.12) / 0.07

Solving for x, we get:

x = 5.12 - 1.645 * 0.07

x ≈ 5.02 ounces

Therefore, the weight that separates the bottom 5% is approximately 5.02 ounces.

These weights could serve as limits used to identify which components should be rejected. Any component with a weight less than 5.02 ounces or greater than 5.22 ounces should be rejected.

The total number of vertices in all the circuits cannot exceed n, and since each circuit contains at least two vertices, the maximum number of circuits is n/2.

The maximum number of vertices that can be contained in an independent set is 0.

(a) In an undirected graph G with n distinct vertices where each vertex has degree 2, the maximum number of circuits that G can contain is n/2. This is because every circuit in the graph will have at least two vertices, and each vertex can only belong to one circuit. Therefore, the total number of vertices in all the circuits cannot exceed n, and since each circuit contains at least two vertices, the maximum number of circuits is n/2.

(b) If all the vertices of G are contained in a single circuit, then there are no independent sets in the graph. An independent set is a set of vertices that are not adjacent to each other. However, in a circuit, every vertex is adjacent to its two neighbours. Therefore, the maximum number of vertices that can be contained in an independent set is 0.

1. There is no solution.

2. The two positive numbers with product 200 such that the sum of one number and twice the second number is as small as possible are 40 and 5.

3. The length and width of the rectangle should be 25 cm and 50 cm, respectively, so that the area is a maximum.

1. Let the two numbers be x and y, where x > y. We have the equation:

x - y = 250

This can be rearranged to give:

x = y + 250

The product of the two numbers is given by:

P = xy = y(y + 250) = y^2 + 250y

To find the minimum value of P, we take the derivative with respect to y and set it equal to zero:

dP/dy = 2y + 250 = 0

Solving for y, we get:

y = -125

Since we require positive numbers, this is not a valid solution. Therefore, we take the second derivative:

d^2P/dy^2 = 2 > 0

This confirms that we have a minimum. To find the corresponding value of x, we use the equation x = y + 250:

x = -125 + 250 = 125

Therefore, the two numbers are 125 and -125, but since we require positive numbers, there is no solution.

2. Let the two numbers be x and y, where x > y. We are given that:

xy = 200

We want to minimize the expression:

x + 2y

We can solve for one variable in terms of the other:

x = 200/y

Substituting into the expression to be minimized, we get:

x + 2y = 200/y + 2y = 200/y + 4y/2 = 200/y + 2y^2/y

Simplifying, we get:

x + 2y = (200 + 2y^2)/y

To minimize this expression, we take the derivative with respect to y and set it equal to zero:

d/dy (200 + 2y^2)/y = -200/y^2 + 4y/y^2 = 4y/y^2 - 200/y^2 = 0

Solving for y, we get:

y = 5

Substituting back into the equation xy = 200, we get:

x = 40

Therefore, the two positive numbers with product 200 such that the sum of one number and twice the second number is as small as possible are 40 and 5.

3. Let the length and width of the rectangle be x and y, respectively. We are given that the perimeter is 100, so:

2x + 2y = 100

Solving for y, we get:

y = 50 - x

The area of the rectangle is given by:

A = xy = x(50 - x)

To maximize this expression, we take the derivative with respect to x and set it equal to zero:

dA/dx = 50 - 2x = 0

Solving for x, we get:

x = 25

Substituting back into the equation y = 50 - x, we get:

y = 25

Therefore, the length and width of the rectangle should be 25 cm and 50 cm, respectively, so that the area is a maximum.

The linear function that models the taxi fare F as a function of the number of miles driven, m can be written as:

F(m) = 2.30 + 0.40(5m - 0.25)

where 5m - 0.25 represents the total distance traveled in fifth of a mile.

To break this down, we start with the base fare of $2.30 for the first quarter of a mile, which is 1.25 fifth of a mile. Then we add the additional distance traveled beyond the first quarter of a mile, which is given by 5m - 0.25. We multiply this by the per-fifth-of-a-mile charge of $0.40.

For example, if a customer travels 2 miles, then the total distance traveled in fifth of a mile would be 10. So, the fare would be:

F(2) = 2.30 + 0.40(5(2) - 0.25) = 2.30 + 3.95 = $6.25

This means that the taxi fare would be $6.25 for a 2-mile ride with the Topology taxi company.

The probability that the geyser will erupt in the next hour is 0.6321 or 63.21%.

To find the probability that the geyser will erupt in the next hour, we can use the exponential distribution formula. The terms involved in this problem are:

1. Exponential distribution

2. Mean time between eruptions (72 minutes)

3. Probability

Step 1: Convert the given hour to minutes. There are 60 minutes in an hour.

Step 2: Calculate the parameter for the exponential distribution. Since the mean time between eruptions is 72 minutes, the parameter (λ) is equal to the reciprocal of the mean, which is 1/72.

Step 3: Use the cumulative distribution function (CDF) formula for the exponential distribution to find the probability of the geyser erupting within the next 60 minutes.

[tex]CDF(x) = 1 - e^{(-λx)}[/tex]

Step 4: Plug in the values into the formula:

[tex]CDF(60) = 1 - e^{(-1/72 * 60)}[/tex]

Step 5: Calculate the result:

[tex]CDF(60) ≈ 1 - e^{(-60/72)} ≈ 1 - e^{(-5/6) }≈ 0.6321[/tex]

By writing the function f(x) as a sum of partial fractions, an explicit formula for the nth Fibonacci number can be derived. The Fibonacci sequence is defined recursively as follows:

F₀ = 0, F₁ = 1, and Fn = Fn-1 + Fn-2 for n ≥ 2.

By expressing the generating function f(x) = x / (1 - x - x²) as a sum of partial fractions, we can obtain a power series representation. Manipulating the resulting series allows us to derive an explicit formula for the nth Fibonacci number.

This approach provides an alternative method to derive the formula and demonstrates the connection between the generating function and the Fibonacci sequence. The explicit formula obtained through this process can be useful in various mathematical and computational applications involving Fibonacci numbers.

To prove that Triangle UTR is similar to Triangle VSR, we must show that all three corresponding angles are congruent and that the corresponding sides are proportional. Here's the 2-column proof:

Statement | Reason
--- | ---
1. ∠UTR ≅ ∠VSR | Given
2. ∠URT ≅ ∠VRS | Vertical angles are congruent
3. ∠RTU ≅ ∠RSV | Vertical angles are congruent
4. ∆UTR ≅ ∆VSR | Angle-Angle (AA) Similarity Theorem

Now, to find the value of x, we can set up a proportion using the corresponding sides UT and VS:

UT/VS = RT/SR

Substituting the given values, we get:

40/25 = (3x+6)/15

Simplifying, we can cross-multiply and solve for x:

600 = 25(3x+6)

600 = 75x + 150

450 = 75x

x = 6

Therefore, the value of x is 6.

BONUS OPPORTUNITY Score: Good job! You earned a perfect score of 5 for your Similarity proof and for solving for x correctly.
To prove that Triangle UTR is similar to Triangle VSR using a 2-column proof, we will first use the Side-Side-Side (SSS) Similarity Theorem. This theorem states that if the corresponding sides of two triangles are proportional, then the triangles are similar.

1. List the given information:
- UR = 40 ft
- RT = (3x + 6) ft
- VR = 25 ft
- SR = 15 ft

2. Write a 2-column proof:

| Statement                    | Reason                         |
|------------------------------|--------------------------------|
| 1. UR = 40 ft                | Given                          |
| 2. RT = (3x + 6) ft          | Given                          |
| 3. VR = 25 ft                | Given                          |
| 4. SR = 15 ft                | Given                          |
| 5. UR/VR = RT/SR             | Using given information        |
| 6. 40/25 = (3x + 6)/15        | Substituting values from 1-4   |
| 7. 8/5 = (3x + 6)/15          | Simplifying the ratio in step 6|
| 8. Triangle UTR ~ Triangle VSR| SSS Similarity Theorem         |

Now that we have proven the triangles are similar, we can find the value of x:

8/5 = (3x + 6)/15

Multiply both sides by 15 to clear the denominator:

15 * (8/5) = (3x + 6)

24 = 3x + 6

Now, subtract 6 from both sides:

24 - 6 = 3x

18 = 3x

Finally, divide both sides by 3 to solve for x:

18 / 3 = x

x = 6

So, the value of x is 6.

For a 95% confidence interval from a sample of size 24, the degrees of freedom is 23. The t-value is 2.069.

To find the t-value for each situation, we need to know the degrees of freedom, which is equal to n-1. Using this information, we can look up the t-value on Table D or use software to find the appropriate value.

a. For a 95% confidence interval based on n = 15 observations, the degrees of freedom is 14. Using Table D, the t-value is 2.145.
b. For a 90% confidence interval from an SRS of 24 observations, the degrees of freedom is 23. Using Table D, the t-value is 1.713.
c. For a 95% confidence interval from a sample of size 24, the degrees of freedom is 23. Using Table D, the t-value is 2.069.

These cases illustrate that as the sample size increases, the t-value decreases, which in turn reduces the size of the margin of error. Additionally, as the confidence level increases, the t-value increases, which increases the size of the margin of error. It is important to note that the size of the margin of error is also affected by the variability of the data, represented by the standard deviation.

To find the t-values for calculating the margin of error for a confidence interval for the mean of the population in the given situations, you can use software or a t-table (Table D) with the appropriate degrees of freedom and confidence level.

a. For a 95% confidence interval based on n = 15 observations, the degrees of freedom are 15-1 = 14. From Table D, the t-value (t*) is approximately 2.145.

b. For a 90% confidence interval from an SRS of 24 observations, the degrees of freedom are 24-1 = 23. From Table D, the t-value (t*) is approximately 1.714.

c. For a 95% confidence interval from a sample of size 24, the degrees of freedom are 24-1 = 23. From Table D, the t-value (t*) is approximately 2.069.

d. These cases illustrate that the size of the margin of error depends on the confidence level and the sample size. As the confidence level increases, the margin of error increases, and as the sample size increases, the margin of error decreases. This is because a higher confidence level requires a larger margin to ensure the true population mean falls within the interval, while a larger sample size provides more accurate estimates, reducing the margin of error.

The values assigned to a population parameter based on the value(s) of a sample statistic are estimations or inferences about the true value of the parameter. These estimations are derived from the sample data and are used to make conclusions about the entire population.

In statistical inference, researchers often collect data from a sample of the population because it is often impractical or impossible to collect data from the entire population. The sample statistics, such as the sample mean or sample proportion, provide information about the characteristics of the sample. However, these statistics are not typically equal to the population parameters they represent.

To estimate the population parameters, researchers use statistical techniques to calculate confidence intervals or conduct hypothesis tests. These techniques allow them to assign a range of plausible values to the population parameter based on the sample statistic. The assigned values take into account the variability of the sample data and the desired level of confidence in the estimation.

For example, if a researcher wants to estimate the average income of a population, they can collect a sample of individuals' incomes and calculate the sample mean. This sample mean is a statistic that provides an estimate of the population mean income. By using statistical techniques, the researcher can assign a range of values, known as a confidence interval, to the population mean based on the sample mean and the variability in the data. The confidence interval provides a level of certainty about the plausible values for the population parameter.

In summary, the values assigned to a population parameter based on a sample statistic are estimations or inferences derived from the sample data. These values are obtained through statistical techniques such as confidence intervals or hypothesis testing, which consider the variability of the sample and provide a range of plausible values for the population parameter. These estimations allow researchers to make conclusions about the population based on the information obtained from the sample.

The function is f: Z → N, defined by f(n) = 2n+1 if n ≥ 0 and f(n) = -2n if n < 0, is a bijection, we need to show that it is both injective (one-to-one) and surjective (onto).

Step 1: Prove injectivity (one-to-one):

Assume f(a) = f(b) for some integers a, b. We need to show that a = b.

Case 1: a, b ≥ 0
f(a) = 2a+1, f(b) = 2b+1
2a+1 = 2b+1 => 2a = 2b => a = b

Case 2: a, b < 0
f(a) = -2a, f(b) = -2b
-2a = -2b => 2a = 2b => a = b

In both cases, f(a) = f(b) implies a = b, so f is injective.

Step 2: Prove surjectivity (onto):

We need to show that for any natural number m, there exists an integer n such that f(n) = m.

If m is odd (m = 2k+1 for some integer k):
n = k => f(n) = 2k+1 = m

If m is even (m = 2k for some integer k):
n = -k => f(n) = -2(-k) = 2k = m

In both cases, we can find an integer n such that f(n) = m, so f is surjective.

Since f is both injective and surjective, it is a bijection.

The equation of the line y = 7x - 4 dilated by a scale factor of 2 centered on the point (1, 3) is y = 7x - 1 in slope-intercept form.

To dilate the line y = 7x - 4 via a scale factor of 2 centered at the point (1, 3), We need to first shift the line in order that its center is on the origin (0, 0), then multiply the x and y coordinates of each factor on the road with the aid of the scale component of two, and finally shift the line back to its original function.

To shift the line so that its middle is at the origin, we want to subtract the coordinates of the center factor (1, 3) from every factor on the line:

y - 3 = 7(x - 1)

Simplifying this equation, we get:

y = 7x - 4

Now, to dilate the line by a scale component of two, we multiply the x and y coordinates of each factor on the line by 2:

2y = 14x - 8

finally, to shift the line back to its original position, we want to add the coordinates of the center factor (1, 3) to each point on the line:

2y = 14x - 8

2(y - 3) = 14(x - 1)

2y - 6 = 14x - 14

2y = 14x - 8 + 6

2y = 14x - 2

Simplifying and rearranging, we get:

b. It would be appropriate and preferable to test H: μ = 15 against the alternative hypothesis H: μ > 15. However, it would be incorrect to do so if we do not have such prior knowledge or if the alternative hypothesis is not supported by the data. I

a) To test the null hypothesis H: μ = 15 against the alternative hypothesis H: μ > 15 using b, we need to calculate the test statistic t, where:

t = (b - μ) / (s / √n)

Here, n = 6, μ = 15, s = 5, and b = 45. Substituting the values, we get:

t = (45 - 15) / (5 / √6) ≈ 10.39

Next, we need to find the p-value associated with this test statistic. Since this is a one-tailed test with the alternative hypothesis being μ > 15, we need to find the area under the t-distribution curve to the right of t = 10.39. Using a t-distribution table or calculator, we find that the area is approximately 0.0001.

Since the p-value is very small, much smaller than the significance level of 0.05, we reject the null hypothesis H: μ = 15 and conclude that there is strong evidence to suggest that the true population mean is greater than 15.

b) It would be appropriate and preferable to test H: μ = 15 against the alternative hypothesis H: μ > 15 if we have strong prior belief or evidence that the true population mean is likely to be greater than 15. In such a case, we would want to conduct a one-tailed test in the direction of the alternative hypothesis.

It would be inappropriate and incorrect to do so if we have no prior belief or evidence that the true population mean is likely to be greater than 15, or if we have reason to believe that it could be less than 15. In such cases, we should use a two-tailed test with the alternative hypothesis H: μ ≠ 15 to avoid the risk of committing a type I error (rejecting a true null hypothesis).

The area of the finite part of the paraboloid z = x^2 y^2 cut off by the plane z = 36 and where y ≥ 0 is infinity.

To find the area of the finite part of the paraboloid[tex]z = x^2 y^2[/tex] cut off by the plane z = 36 and where y ≥ 0, we need to first determine the bounds of integration.

Since the plane z = 36 intersects the paraboloid z = x^2 y^2 at z = 36, we can substitute z = 36 into the equation for the paraboloid to get:

36 = x^2 y^2

Solving for y, we get:

y = ± 6/x

However, since we are only interested in the part of the paraboloid where y ≥ 0, we only need to consider the positive root:

y = 6/x

Now we need to determine the bounds of integration for x. We know that the paraboloid is symmetric about the z-axis, so we only need to consider the positive values of x. The paraboloid intersects the yz-plane (where x = 0) at y = 0, and as y increases, the value of x decreases. We can find the maximum value of x by setting y = 0 in the equation for the paraboloid:

z = x^2 y^2

z = x^2 (0)^2

z = 0

So the maximum value of x is when z = 36:

36 = x^2 (0)^2

x = ∞

Since x approaches infinity, we can use x = a as the lower bound of integration, where a is some very large positive number.

Therefore, the bounds of integration are:

∫[a, ∞]∫[0, 6/x] (36 - x^2 y^2) dy dx

We can now evaluate the double integral:

∫[a, ∞]∫[0, 6/x] (36 - x^2 y^2) dy dx

= ∫[a, ∞] (36y - x^2 y^3 / 3) |_0^6/x dx

= ∫[a, ∞] (36(6/x) - x^2 (6/x)^3 / 3) dx

= ∫[a, ∞] (216/x - 72/x^5) dx

= [216 ln|x| + 12/x^4]_a^∞

= 216 ln|∞| + 12/∞^4 - 216 ln|a| - 12/a^4

= ∞ - 0 - (-∞) - 0

= ∞

So the area of the finite part of the paraboloid z = x^2 y^2 cut off by the plane z = 36 and where y ≥ 0 is infinity.

The point estimate and standard error for the proportion of adults who are getting the recommended amount of sleep each night are  0.560 and 0.048 respectively.

The point estimate for a proportion is the sample proportion, which in this case is 56/100 = 0.56. This means that 56% of the adults in the sample reported getting the recommended amount of sleep.

The standard error measures the variability in the sample proportion due to sampling error. It tells us how much we would expect the sample proportion to vary from the true population proportion if we took many different samples of the same size.

The standard error for the proportion can be calculated using the formula:

SE = √(p'(1-p')/n)

where n is the sample size. Substituting the given values:

SE =√(0.56(1-0.56)/100) ≈ 0.048

Rounding to three decimal places, the point estimate is 0.560 and the standard error is 0.048.

Based on the given integral, we can use the formula for integrating e^x, which is e^x.

To evaluate it, we simply plug in the values for e^(1.6) and e^(-1.4) and subtract them:
e^(1.6) - e^(-1.4) ≈ 7.355 - 0.245 ≈ 7.11

Therefore, the final answer is convergent and equals approximately 7.11.
To determine if the given integral is divergent or convergent and to evaluate it if convergent, we need to follow these steps:
1. Identify the integral from the provided information.
From the given question, we can infer that the integral is:
∫(e^x) dx from -1.4 to 1.6

2. Evaluate the integral.
To evaluate this integral, we need to find the antiderivative of e^x. The antiderivative of e^x is e^x itself. So, we will evaluate e^x from -1.4 to 1.6.

3. Apply the Fundamental Theorem of Calculus.
The Fundamental Theorem of Calculus states that:
∫(e^x) dx from -1.4 to 1.6 = e^1.6 - e^(-1.4)

4. Check for convergence or divergence.
Since e^x is a continuous function, and we have finite limits of integration, the integral converges.

5. Calculate the final value.
Now, we just need to substitute the values and compute the result:
e^1.6 - e^(-1.4) ≈ 4.953032 - 0.246597 ≈ 4.706435

So, the integral is convergent and its value is approximately 4.706435.

Converting complex numbers from rectangular form (a + bi) to polar form (r∠θ), we get A = √13 ∠ 56.3° in polar form.

we use the following formulas:

r = √(a^2 + b^2)
θ = tan^-1(b/a)

For D = 1 - j2:
a = 1, b = -2
r = √(1^2 + (-2)^2) = √5
θ = tan^-1(-2/1) = -63.4° (or 296.6° in polar coordinates)

Therefore, D = √5∠296.6° in polar form.

For A = 2 + j3:
a = 2, b = 3
r = √(2^2 + 3^2) = √13
θ = tan^-1(3/2) = 56.3°


To convert the complex numbers D = 1 - j2 and A = 2 + j3 to polar form, we first find their magnitudes (r) and angles (θ) using the formulas:

r = √(x^2 + y^2)
θ = arctan(y/x)

For D (1 - j2):
r_D = √((1)^2 + (-2)^2) = √(1 + 4) = √5
θ_D = arctan((-2)/1) = -63.4° (approx.)

So, D in polar form is: D = √5 ∠ -63.4°

For A (2 + j3):
r_A = √((2)^2 + (3)^2) = √(4 + 9) = √13
θ_A = arctan(3/2) = 56.3° (approx.)

So, A in polar form is: A = √13 ∠ 56.3°

The coordinates for a similar triangle DEF by dilating triangle ABC with respect to the origin using a scale factor of √5/2.

In this case, we can choose any point as the center of dilation, but for simplicity, let's choose the origin (0,0). This means that we will stretch or shrink triangle ABC with respect to the origin.

This point has coordinates (2s, s), where s is the scale factor. To see why, consider that the distance from the origin to the point (2s, s) is given by the Pythagorean theorem as:

√((2s)² + s²) = s√5

This distance should be 2 times the scale factor, so we have:

s√5 = 2s

Solving for s, we get:

s = √5/2

Therefore, the corresponding side of triangle DEF is the line passing through (0,0) and (2√5, √5). Similarly, we can find the corresponding sides for the other two sides of triangle ABC to get the complete set of coordinates for triangle DEF.

The area of the region that lies inside the circle r=3sinΘ and outside the cardioid r=1+sinΘ is 9π/4 - √3/2.

To find the area, we first need to determine the values of θ at which the two curves intersect. Setting r=3sinΘ equal to r=1+sinΘ, we get sinΘ = 1/2, which gives Θ = π/6 and Θ = 5π/6.

Next, we can use the area formula for polar coordinates: A=1/2∫βα(f(θ))2dθ. Since the cardioid is inside the circle for Θ between π/6 and 5π/6, we need to find the area of the circle minus the area of the cardioid. Thus, we have:

A = 1/2 [(∫0^(π/6) (3sinΘ)^2 dΘ) + (∫5π/6^π (3sinΘ)^2 dΘ) - (∫π/6^(5π/6) (1+sinΘ)^2 dΘ)]

Simplifying and evaluating the integrals, we get: A = 9π/4 - √3/2

Answer: he travel 80 minutes in the first 4 minutes the bike was stationary for 2 minutes

From the graph we get,

(a) Mr. Bond travelled 80 meters in the first 4 minutes.

(b) For 2 minutes (From 4th minute to 6th minute) the bike was stationary.

(c) Mr. Bond was travelling at greatest speed from 6th minute to 8th minute.

(d) The greatest speed of the car was 50 meters/min.

In given graph, X axis refers to time in minutes and Y axis refers to the distance along road in meters.

Here (4, 80) is a point on the graph.

So, in 4 minutes Mr. Bond rode 80 meters on road.

From 4 to 6 minutes the distance travelled by bike remain same that 80 meters.

Hence, for (6 - 4) = 2 minutes the bike was stationary.

The speed from 0 minute to 4 minutes was = (80 - 0)/(4 -0) = 80/4 = 20 meters/min.

From 4 minutes to 6 minutes the speed remained same.

From 6 minute to 8 minute the speed was = (180 - 80)/(8 - 6) = 100/2 = 50 meters/min.

From 8 minute to 10 minute the speed was = (220 - 180)/(10 - 8) = 40/2 = 20 meters/min.

Hence the Mr. Bond was travelling at greatest speed at 6 to 8 minutes.

So, the greatest speed of the car = 50 meters/min.
