    1/2 of a block

    Step-by-step explanation:

    Use proportions to solve

    7.5 blocks / 15 minutes = x blocks / 1 minute

    7.5=15x

    x=.5

    1. Multiply the numerators by the other's denominator (7.5*1 will equal to 15*x) ( * means times)

    2. Isolate x by dividing 7.5=15x by 15 and you will have what x equals.
