Answer:

85 miles per hour.

Explanation:

We have been given a formula
r=(d)/(t) , d is the distance in miles, r is the rate, and t is the time in hours.

To find the rate, we will substitute our given values in above formula as:

$r=\frac{\text{212.5 miles}}{\text{2.5 hours}}$

$r=\frac{\text{85 miles}}{\text{ hour}}$

Therefore, our required rate is 85 miles per hour.
