    A boat can row downstream at 24 km and upstream 16 km in

    8 hours. Then what is the velocity of the current ?
    A 1 / 3 km /hr Correct Answer Incorrect Answer
    B 1 / 2 km /hr Correct Answer Incorrect Answer
    C 1 / 7 km /hr Correct Answer Incorrect Answer
    D 1 / 4 km /hr Correct Answer Incorrect Answer

    Solution

    The rate of downstream = 24 / 8 km/hr , The rate of upstream = 16 / 8 km /hr . So , the velocity of the current is 1 / 2 ( 24 / 8 – 16 / 8 ) km /hr = 1 / 2 km /hr.
