    They would be 132km apart

    Step-by-step explanation:

    In order to solve this we need to set up a proportion. To make that easier, let's first change the fractions into decimals.

    2 1/2 = 2.5

    5 1/2 = 5.5

    Now we can put the scale in the right side fraction and the distance in the left.

    2.5cm/60km = 5.5cm/xkm

    Now cross multiply to solve

    60 * 5.5 = 2.5 * x

    330 = 2.5x

    132 = x
