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?

Explanation:

Step1: Set up the ratio

We know that 4 inches on the map represents 2 miles in actual - distance. Let the multiplier be $x$. The ratio is $\frac{2\text{ miles}}{4\text{ inches}}$.

Step2: Simplify the ratio

$\frac{2}{4}=\frac{1}{2}$ mile per inch. So we multiply each length on the map (in inches) by $\frac{1}{2}$ mile per inch to get the actual distance (in miles).

Answer:

$\frac{1}{2}$
