The distance between two cities on a map is 15 inches. If the scale is 0.25 inches = 3 miles, how many miles apart are the actual cities?

Since we know that 1/4 of an inch is 3 miles,

then if we times 4 from both sides, then we get 1 inch = 12 miles

Since the cities distance is 15 inches, we times 1 by 15 and 12 by 15

1 x 15 = 15, and 12 x 15 = 180

so its 180 miles
