The scale of a map is 0.25 cm : 15 mi. determine the distance between two cities that are 6.8 cm apart on the map

Divide the actual distance of the scale by the map distance of the scale, which is 15/0.25 = 60. This shows that the scale is 1 cm:60 miles.

If the distance between two cities on a map is 6.8 cm, multiply by 60 to get the real distance between the two cities in miles, which is 408 miles.

408 miles

Hope this helped!
