Question

    Bus 'X' and Bus 'Y' start together from a station heading

    in the same direction. Bus 'X' moves at 18 km/h while Bus 'Y' moves at 30 km/h. Determine the distance between them after 150 seconds.
    A 300 m Correct Answer Incorrect Answer
    B 200 m Correct Answer Incorrect Answer
    C 500 m Correct Answer Incorrect Answer
    D 400 m Correct Answer Incorrect Answer

    Solution

    ATQ,

    Relative speed of Bus 'Y' w.r.t Bus 'X' = 30 - 18 = 12 km/h

    So, distance covered in 150 seconds = 12 × (5/18) × 150 = 500 metres
