    Question

    The time taken by a boat to

    travel (5p + 60) km upstream is equal to the time taken to travel (8p - 40) km downstream. Given that the speed of the boat is 50 km/h and the speed of the stream is 5 km/h, determine the value of 'p'.
    A 60 km Correct Answer Incorrect Answer
    B 42 km Correct Answer Incorrect Answer
    C 34 km Correct Answer Incorrect Answer
    D 25 km Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, So, (5p + 60)/ (50 – 5) = (8p – 40)/(50 + 5) 275p + 3300 = 360p – 1800 85p = 5100 p = 60 So, the value of ‘p’ is 60 km
