Question

The length of the freeway is 600 miles. If 0.5 inch represents 50 miles, what is the length of the freeway on the map ?

Answer 1

How many 50 miles are in 600 miles :
600 miles / 50 miles = 12
There are 12 slices of 50 miles in 600 miles.

1 slice of 50 miles equals 0.5 inch
(1 slice × 0.5 inch = 0.5 inch)
so
12 slices of 50 miles equals 6 inches
(12 slices × 0.5 inch = 6 inches)

The lenght of the freeway on the map is 6 inches.
