    Answer:

    1 1/9 miles

    Step-by-step explanation:

    If john swims 5/12 of a mile in 3/8 of an hour, then;

    5/12 miles = 3/8 hours

    TO get the number of miles he swims in an hour, we will say;

    x miles = 1 hour

    Equating both expressions

    5/12 miles = 3/8 hours

    x miles = 1 hour

    Cross multiply

    3/8 x = 5/12

    3x/8 = 5/12

    3x * 12 = 5 * 8

    36x = 40

    x = 40/36

    x = 10/9

    x = 1 1/9

    The amount he swims in an hour is 1 1/9 miles
