Using the formula , 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?

1 answer

The formula that relates distance, rate, and time is:

d = r*t

We want to find the rate (r), so we can rearrange the formula to solve for r:

r = d/t

Given that the distance (d) is 212.5 miles and the time (t) is 2.5 hours, we can substitute these values into the formula to find the rate:

r = 212.5/2.5

Simplifying the expression:

r = 85

Therefore, you must travel at a rate of 85 miles per hour to cover 212.5 miles in 2.5 hours.
