    Question

    How far will 'Arjun' travel by the time he catches up to

    'Rohan', given that 'Arjun' starts 150 km behind and moves at 55 km/h while 'Rohan' moves at 35 km/h?
    A 420 km Correct Answer Incorrect Answer
    B 575 km Correct Answer Incorrect Answer
    C 270 km Correct Answer Incorrect Answer
    D 300 km Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Relative speed of 'Arjun' w.r.t 'Rohan' = 55 - 35 = 20 km/h

    Time taken by 'Arjun' to overtake 'Rohan' = (150/20) = 7.5 hours

    So, distance covered by 'Arjun' in 7.5 hours = 55 × 7.5 = 412.5 km
