Answer:
85 miles per hour.
Step-by-step explanation:
We have been given a formula \(r=\frac{d}{t}\), 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.
