Question

The distance between City A and City B is 500 miles. A length of 1.8 feet represents this distance on a certain wall map. City C and City D are 2.16 feet apart on this map. What is the actual distance between City C and City​ D?

Answer 1

600 miles

Explanation:

The actual distances between the cities are expected to be proportional to those on the map.

__

AB/(1.8 ft) = CD/(2.16 ft) . . . . ratio of miles to feet is constant

CD = AB(2.16 ft)/(1.8 ft) = (500 mi)(6/5)

CD = 600 mi

The actual distance between City C and City D is about 600 miles.
