Question

On a world map, the distance between city A and city B is 4.357 inches. The two cities are actually 1313 miles apart. On the same map, what would be the distance between city C and city D, two cities that are actually 1659 miles apart?

Answer 1

This is a proportion:

 

4.357 / 1313 = x / 1659

(1659) (4.357) / 1313 = x

7228.263 / 1313 = x

5.50515080 = x

 

The distance on the map is 5.505 inches.
