Explanation:

Step1: Identify the scale

The scale is 4 in. : 2 mi, which can be simplified to 2 in. : 1 mi. This means 2 inches on the map represents 1 mile in actual - distance.

Step2: Measure the map - distance

The map - distance from the campsite to the general store is 3 inches.

Step3: Set up a proportion

Let $x$ be the actual distance. The proportion is $\frac{2}{1}=\frac{3}{x}$.

Step4: Solve the proportion

Cross - multiply: $2x = 3\times1$. Then $x=\frac{3}{2}=1.5$ mi.

Answer:

The actual distance from the campsite to the general store is 1.5 mi.
