    Bus A starts from Ambala at 9.00 am and reaches Amritsar at 11.00 am. Another bus B starts from Amritsar at 9.00 am and reaches Ambala at 10.00 am. At what time will they cross each other?
    Solutions

    Let the distance between Ambala and Amritsar be 2x km

    Then speed of bus A = 2x/2 = x km/hr

    and speed of bus B = 2x/1 = 2x km/hr

    Relative speed = x + 2x = 3x km/hr

    Time taken for meeting = 2x/3x = 0.66 hours = 40 min
