Question

The graph represents Jason's speed on a trip. What is the rate of change for the period of time between 10 and 20 minutes?

A) 0

B) 1

C) 12

D) 13

Answer 1

From 10 minutes to 20 minutes there is no rate of change, it stays at a constant and steady rate

Your answer would be A) 0

Answer 2

Option A - 0

Explanation:

Given : The graph represents Jason's speed on a trip.

To find : What is the rate of change for the period of time between 10 and 20 minutes?

Solution :

The rate of change is defined as the division of change in speed by change in time.

Now, the rate of change for the period of time between 10 and 20 minutes is

Speed in 10 minutes is 50 mph

Speed in 20 minutes is 50 mph

The rate of change is
`r=(s_2-s_1)/(t_2-t_1)`

`r=(50-50)/(20-10)`

`r=0`

Therefore, Option A is correct.

The rate of change for the period of time between 10 and 20 minute is 0 or constant as shown graphically.
