    Question

    A motorboat covers 96 km downstream in 4 hours. Coming back

    upstream over the same distance, it takes 8 hours longer than the downstream time. Find the speed of the boat in still water.
    A 10 km/hr Correct Answer Incorrect Answer
    B 26 km/hr Correct Answer Incorrect Answer
    C 16 km/hr Correct Answer Incorrect Answer
    D 23 km/hr Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Downstream speed = 96 / 4 = 24

    Upstream speed = 96 / 12 = 8

    V + U = 24

    V – U = 8

    By solving, we get V = (24 + 8) / 2 = 16 km/hr
