    19 hrs

    Step-by-step explanation:

    t varies inversely with number of people p

    t = k/p

    If it takes 7.125 hrs for 8 workers to do the job

    K = tp

    = 7. 125 x 8

    = 57

    How many hours will it take if there are 3 workers.

    Recall t = k/p

    t = 57/3

    = 19 hrs

    Therefore, It'll take 19 hrs to Complete the job if there are only three workers.
