Debra can run 20 1/2 miles in 2 1/4 hours. how many miles per hour can she run?

She can run

Step-by-step explanation:

It is required to estimate the velocity of Debra.

Debra can run 20 1/2 miles. It means d = 20 1/2 miles = 41/2 miles.

Debra runs the distance previously presented in 2 1/4 hours.

It means t = 2 1/4 hours = 9/4 hours.

Now, we have the distance (d), and the time requiered (t) in which Debra can run. Finally, to calculate the velocity we need to divide the distance by the time.

Debra can run 82/9 miles per hour.
