    The answer to your question is when time = 50 s, work = 5000 J

    when time = 90 s, work = 9000 J

    Explanation:

    Data

    time = 50 s or 90 s

    Power = 100 watts

    Power is defined as the rate of work done per unit of time.

    Power = Work / time

    -Solve for Work

    Work = Power x time

    -Substitution

    Work = 100 x 50

    -Result

    Work = 5000

    2.-When time = 90 s

    Work = 100 x 90

    -Result

    Work = 9000 watts
