Explanation:

Step1: Recall division - fraction rule

To find the unit - rate of miles per gallon, we divide the number of miles by the number of gallons. When dividing by a fraction, we multiply by its reciprocal. So, $\frac{\frac{15}{4}}{\frac{1}{5}}=\frac{15}{4}\times5$.

$\frac{15}{4}\times5=\frac{15\times5}{4}=\frac{75}{4}=18.75$.

Answer:
