On a map of the United States, 1 inch represents a distance of 50 miles. If the distance between New Town and Old Town is 450 miles, how far apart are they on the map?

A. 2.5 inches

B. 8.3 inches

C. 9 inches

D. 12 inches

Solution

C. The basic question is that if 1 inch = 50 miles, how many inches = 450 miles? Set this up as a proportion.  1/50 = x/50 Cross-multiply and solve for x. 50x = 450. x = 9. So the distance on the map between New Town and Old Town is 9 inches.
