Question

Suppose the distance between two cities on a map is 5.2 inches . The scale is 1 inch = 80 miles . What’s the actual distance between the cities ?

Answer 1

416 miles

Explanation:

Set up a proportion to solve this...

1 inch is to 80 miles, as 5.2 inches is to 'x' miles

1/80 = 5.2/x now solve for x by cross multiplying

x = 416
