    The correct answer is c. T/p=k

    Step-by-step explanation:

    If time (t) is directly related to the number of people (p)

    We can say that

    t = k p or k=t/p or p = t/k

    The options given are:

    P/t=k incorrect

    K/t=p incorrect

    T/p=k correct

    P/k=t incorrect

    Step-by-step explanation:

    The time is inversely related to the number of people working so that as the number of people working increases, the time required decreases

    t = k p

    divide both sides by p

    t/p = k
