The distance between city A and city B is 500 miles. On a certain wall map, this is represented by a length of 2.3 feet. On the map, how many feet would there be between city C and city D, two cities that are actually 800 miles apart?
On the map, city C and city D are ___ feet apart.

Cross multiply and solve for x.
500/2.3 = 800/x
