    Question

    A man can swim downstream in 12 minutes covering a

    distance of 600 meters. He takes 15 minutes to cover the same distance upstream. Find the speed of the stream in meters per minutes.
    A 2 m/min Correct Answer Incorrect Answer
    B 1.5 m/min Correct Answer Incorrect Answer
    C 3 m/min Correct Answer Incorrect Answer
    D 3.75 m/min Correct Answer Incorrect Answer
    E 5 m/min Correct Answer Incorrect Answer

    Solution

    Downstream speed = 600 ÷ 12 = 50 m/min. Upstream speed = 600 ÷ 15 = 40 m/min. Speed of stream = (Downstream speed - Upstream speed) ÷ 2 = (50 - 40) ÷ 2 = 10 ÷ 2 = 5 m/min. Correct Option: e) 5 m/min
