The lenten on a map states that 1 inch is 40 miles. If you measure 5 inches on the map, how many miles would the actual distance be?

Work Shown:

(1 inch)/(40 miles) = (5 inches)/(x miles)

1/40 = 5/x

1*x = 40*5 cross multiply

x = 200 miles

We could also look at it like this:

1 inch = 40 miles

5*(1 inch) = 5*(40 miles) multiply both sides by 5

5 inches = 200 miles
