5-108.

Zeke ran $4$ miles in $45$ minutes. If he keeps running at the same pace, how long will it take him to run $10$ miles? What is his unit rate in miles per hour?

A proportion can be used to solve this.

$\frac{\text{4 miles}}{\text{45 minutes}}=\frac{\text{10 miles}}{x\text{ minutes}}$

To find the unit rate, consider another proportion where one ratio is $\frac{x \text{ miles}}{\text{60 minutes}}$
