Question

A map is drawn to a scale of 1/2 inch = 20 miles How many miles apart are two cities that are 3 1/4 inches apart on the map?​

Answer 1

Answer:   130 miles

Work Shown:

1/2 = 0.5

1/4 = 0.25

0.5 inch = 20 miles, which is the given scale

1 inch = 40 miles, after multiplying both sides by 2

3.25 inches = 130 miles after multiplying both sides by 3.25
