Question

On a certain map, 1 inch represents a distance of 10 miles how many miles apart are two towns that are 3 inches apart on the map

Answer 1

30 miles apart.

Explanation:

The scale for the map is 1 inch represents a distance of 10 miles.

That is 1 inch : 10 miles.

We want to find the number of miles two towns are apart, if they are 3 miles apart on the map.

We just have to multiply each term in the ratio by 10 to get:

3 inches: 30 miles

Therefore the two towns will be 30 miles apart.
