In the formula rt = d, r is is rate t is time, and d is distance what is the rate for a runner who complete 7.5 miles in 1.5 hours?

The rate is 5 miles per hour

Step-by-step explanation:

First thing off we need to get r alone. We can do this by dividing both sides by t. Lets do so

rt/t=d/t

Simplfy

r=d/t

Now input the known value for d and t

r=7.5/1.5

Divide

r=5

The rate is 5 miles per hour

r = 5 miles per hour

Step-by-step explanation:

rt = d

We want to solve for r

Divide each side by t

rt/t = d/t

r = d/t

We know the distance is 7.5 miles and the time is 1.5 hours

r = 7.5 miles / 1/5 hours

r = 5 miles per hour
