Question

On a map, the length of the road from town A to B is 12 inches. On this map, ¾ inch represents 8 miles. What is the actual distance from town A to B in miles?

Answer 1

128 miles

You can get this by setting up a proportion. 

.75/8 = 12/x

Then cross multiply

12*8 = .75 x
96 = .75x
128 = x
