Answer:

5 miles per 1 hour

Step-by-step 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.

[tex]\frac{3\frac{1}{8} }{\frac{5}{8} }  = 3\frac{1}{8} * \frac{8}{5}  = \frac{25}{8} *\frac{8}{5} =\frac{200}{40}  = 5[/tex]

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