    Answer:

    5.2 s

    Explanation:

    From the question given above, the following data were obtained:

    Velocity = 7.5 m/s

    Displacement = 39 m up

    Time =?

    The time taken for the cable cab to get to 39 m can be obtained as follow:

    Velocity = Displacement / Time

    7.5 = 39 / time

    Cross multiply

    7.5 × time = 39

    Divide both side by 7.5

    Time = 39 / 7.5

    Time = 5.2 s

    Thus, the time taken for the cable cab to get to 39 m up is 5.2 s
