The scale is:
For every 1 inch on the map, the actual distance is 6 miles.
The distance between 2 towns on the map = 2.5 inches.
Using the given scale we can convert it to actual distance between the two towns.
So, the actual distance between two towns = ( 2.5 x 6 ) miles = 15 miles
Therefore, the two towns are 15 miles apart.
