    Answer:

    6 runners

    Step-by-step explanation:

    Complete question

    A relay race covers 1 1/2 kilometers, and each runner on a team will run 1/4 of a kilometer.  How many runners are needed for a team?

    Given that;

    1 runner = 1/4 km

    If a relay race covers  1 1/2 km, hence;

    x runner = 1 1/2 km

    Divide both expressions

    1/x = (1/4)÷(1 1/2)

    1/x = 1/4 ÷ 3/2

    1/x = 1/4 * 2/3

    1/x = 2/12

    Cross multiply

    2x = 12

    x = 12/2

    x = 6

    Hence 6 runners are needed for the race
