On a map, two cities are 5.625 inches apart.

Question

If .375 on the map represents 100 miles, find the number of miles between the two cities. 

Answer 1

This can be solved using a proportion:

 

100/0.385 = m/5.625, where m = miles the city are apart

0.025974 = m/5.625

1461 = m

 

The cities are 1,461 miles apart.
