    Question

    The time to travel (x – 35) km upstream is the same as

    the time for (2x – 115) km downstream. Given the boat’s speed is 11 km/h and the stream’s speed is 2 km/h, find ‘x’.
    A 125 km Correct Answer Incorrect Answer
    B 116 km Correct Answer Incorrect Answer
    C 155 km Correct Answer Incorrect Answer
    D 120 km Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    (x – 35)/(11 – 2) = (2x – 115)/(11 + 2)

    (x – 35)/9 = (2x – 115)/13

    13x – 455 = 18x – 1035

    5x = 580 → x = 116

    So, the value of ‘x’ is 116 km.
