Answer:
600 miles
Step-by-step 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.
