Answer:
30 miles apart.
Step-by-step 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.
