Answer 1

5 miles per 1 hour

Explanation:

A unit rate is a comparison of a value per 1. This means the denominator of the fraction is 1.

To find it, write a ratio between miles and hours as 3 1/8 miles per 5/8 hours. To make it a unit rate, divide the two values.

`(3(1)/(8) )/((5)/(8) )  = 3(1)/(8) * (8)/(5)  = (25)/(8) *(8)/(5) =(200)/(40)  = 5`

This means the unit rate is 5 miles/ 1 hour.
