Question

. Find the rate of change for the situation.

You run 7 miles in one hour and 14 miles in two hours.

A.7 miles per hour

B.2 hours

C.7 miles

D.2 miles per hour

Answer 1

The answer is A.
To find speed/rate of change, divide distance by time.
7 mi/ 1 hr= 7 mph
14 mi/2 hr= 7mph

Answer 2

Answer: A.7 miles per hour

Explanation:

Given: You run 7 miles in one hour and 14 miles in two hours.

We know that

The rate of change of function=
`\frac{\text{change in distance}}{\text{change in time}}`

Therefore, the rate of change of function for the given situation

`=(14-7)/(2-1)=(7)/(1)`

Hence the rate of change of function for the given situation= 7 miles per hour.
