Divide both sides by 4:

The distance between Dallas and Fort Worth on a map is 7.5 centimeters. The map uses a scale in which 1 centimeters represents 3
anyanavicka [17]

Hi There


To find the distance, you have to make them proportional to each other.


1 cent.  / 30 kilo. = 7.5 cent. / x


Then you cross multiply.


30 x 7.5 = x


225 = x


The distance between the two cities is 225 kilometers.


Hope that helps:)
