The graph shows the distance in miles of a runner over x hours. What is the average rate of speed over the interval [9, 11]?

ELEN [110]

Question:

The graph shows the distance in miles of a runner over x hours. What is the average rate of speed over the interval [9, 11]?

A. 2/5

B. 1

C.2

D.5/2

The image of the graph is attached below.

Answer:

Option D: 5/2 is the average speed over the interval [9,11]

Explanation:

The graph shows the distance in miles of a runner over x hours.

Now, we need to determine the average rate of speed over the interval $[9,11]$

The x-axis represents the time taken.

The y-axis represents the distance.

To find the average speed, let us use the formula for speed which is given by

$speed=\frac{distance}{time}$

Thus, substituting the coordinates $(9,6)$ and $(11,11)$ , we have,

$speed=\frac{11-6}{11-9} =\frac{5}{2}$

Hence, the average speed over the interval $[9,11]$ is $\frac{5}{2}$

A company borrowed $25,000 at 3.5% and was charged $2,625 in interest. How long was it before the company repaid the money?

nirvana33 [79]

Hello

3 years. Since no mention of compounding was made I will assume that it's 3.5% simple interest. So first, let's calculate what percent of the entire loan was interest. Just a simply matter of division. 2625 / 25000 = 0.105 = 10.5% Now lets' divide the percentage of the loan that was paid in interest by the interest rate. 10.5% / 3.5% = 3 So the company took 3 years to repay the loan.
