Step 1: Let's review the information given to us to answer the exercise correctly
Scale of the map : 1 inch = 18 miles
Distance between 2 towns in the map = 2 inches
Step 2: Let's solve the equivalent to 2 inches on the map using Direct Rule of Three, as follows:
inches miles
1 18
2 x
______________
1 * x = 18 * 2
x = 36
Step 3: Interpret the value founded
On the map, the towns that are 2 inches apart, actually are 36 miles away.
