Question

oscar has a map of the campground where he is staying. the scale shows that 4 inches on the map represents an actual distance of 2 miles. oscars tent is at campsite 4a. what number can you multiply each length on the map by to find the actual distance? what is the actual distance from oscars campsite to the general store? 4 in.: 2 mi

Explanation:

Step1: Identify the scale ratio

The scale is 4 inches : 2 miles, which simplifies to 2 inches : 1 mile or $\frac{1\text{ mile}}{2\text{ inches}}$.

Step2: Determine the map - distance to the store

The map - distance from Oscar's tent (at campsite 4A) to the general store is 3 inches.

Step3: Calculate the actual distance

Let $d$ be the actual distance. We use the proportion $\frac{d}{3\text{ inches}}=\frac{1\text{ mile}}{2\text{ inches}}$. Cross - multiplying gives $d=\frac{3\times1}{2}= 1.5$ miles.

Answer:

1.5 miles
