    Question

    How far will 'Neha' travel by the time she catches up to

    'Simran', given that 'Neha' starts 75 km behind and moves at 60 km/h while 'Simran' moves at 45 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

    Solution

    ATQ,

    Relative speed of 'Neha' w.r.t 'Simran' = 60 - 45 = 15 km/h

    Time taken by 'Neha' to overtake 'Simran' = (75/15) = 5 hours

    So, distance covered by 'Neha' in 5 hours = 60 × 5 = 300 km
