    The direction in which the speed is maximum, is:

    A) upstream

    B) downstream

    C) both have equal speed

    D) None of these  

    Correct Answer: B

    Solution :

    In downstream, the speed is maximum because in downstream, the speed is \[(x+y)\,km/h\] and in upstream, the speed is\[(x-y)\,km/h\].
    So, option [b] is correct.
