Question

Using the formula r=d/t, where d is the distance in miles, r is the rate, and t is the time in hours, at which rate must you travel to cover 212.5 miles in 2.5 hours?

Answer 1

r=d/t = 212.5/2.5 = 85

Answer 2

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.
