The scale on a map shows that 1 inch = 30 miles. If there are 4.5 inches between your present location and the place you want to

anastassius [24]

Scale : 1 inch = 30 miles

So, the ratio between the distance on the map and the real distance is 1:30

When a quantity increase/decrease in a ratio, the other one increase/decrease respectively.

Call the miles we have to go : x

1:30 = 4.5:x

(1x4.5):(30x4.5) = 4.5 : x

4.5 : 135 = 4.5 : x

So, x = 135 => We have to go 135 miles to get to the place we want to go.
