Explanation:

Step1: Set up scale - ratio

The scale is 4 inches : 2 miles. We want to find the multiplier for 1 - inch on the map to get actual distance in miles. Let the multiplier be $x$. The ratio is $\frac{4}{2}=\frac{1}{x}$.

Step2: Solve for $x$

Cross - multiply: $4x = 2$. Then $x=\frac{2}{4}=\frac{1}{2}$.

Answer:
