A map has a scale of 5 inches : 12 miles. If two cities are 13 inches apart on the map, what is the actual distance between the cities, to the nearest mile

13 in / 5/12 in/mile   = 13 * 12/5 miles  = ........ miles

5 / 12  =  13/ x     cross-multiply

 

5x  =  13 * 12

 

5x   = 156        divide both sides  by  5

 

x   =156/5  = 31.2  miles  =    31 miles
