Answer
12.5 miles per hour
Work Step by Step
We start with the rate: 2.5 miles per 12 minutes. Thus, we need to use unit conversions to solve. We find:
$\frac{2.5 miles}{12 minutes} \times \frac{60 minutes}{hour} =12.5$ miles per hour.
Note, we need to cancel out the unit of minutes, so we multiply by a fraction with minutes in the numerator as our first fraction has minutes in the denominator.
