Question

A runner runs 8 miles in 92 minutes. What is the runners unit rate?

Answer 1

The runners unit rate is in miles per hour, or miles per minute.92 minutes = 1.53 h8 mi : 1.53 h = 5.22 mi / hour5.22 mi / h : 60 = 0.087 mi/minAnswer: 5.22 mi/h or 0.087 mi/min

Answer 2

For this case, what we must do is calculate the speed of the runner.

We have then that the speed is given by:

`image`

Where,

d: distance

t: time

Substituting values we have:

`v = (8)/(92)`

`V = 0.09 (miles)/(minutes)`

Answer:

the runners unit rate is:

`V = 0.09 (miles)/(minutes)`
