The scale on a map is 1 inch = 200 miles what is actual distance in mile 3/8 inch represent?

Answer 1

You could use a ratio 1 inch/200 miles = (3/8) inch/x miles

Solving for x: x = (3/8)200 = 75 miles

or you could just write

1 inch = 200 miles

then multiply by (3/8): (3/8)(1 inch = (3/8)(200 miles)

or (3/8) inch = 75 miles
