Q:
# 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. 2/5B. 1C.2D.5/2

Accepted Solution

A:

For this case what you should see is that for the interval [9, 11] the behavior of the function is almost linear.

Therefore, we can find the average rate of change as follows:

m = (y2-y1) / (x2-x1)

m = (11-6) / (11-9)

m = (5) / (2)

m = 5/2

Answer:

the average rate of speed over the interval [9, 11] is:

D. 5 / 2

Therefore, we can find the average rate of change as follows:

m = (y2-y1) / (x2-x1)

m = (11-6) / (11-9)

m = (5) / (2)

m = 5/2

Answer:

the average rate of speed over the interval [9, 11] is:

D. 5 / 2
