  • Question
  • Two stations A and B are 110 km apart on a straight line. One train starts from A at 7 a.m. and travels towards B at 20 kmph. Another train starts from B at 8 a.m. and travels towards A at a speed of 25 kmph. At what time will they meet?


  • Options
  • A. 9 a.m.
  • B. 10 a.m.
  • C. 10.30 a.m.
  • D. 11 a.m.

  • Correct Answer
  • 10 a.m. 

    Explanation
    Suppose they meet x hours after 7 a.m.

    Distance covered by A in x hours = 20x km.

    Distance covered by B in (x - 1) hours = 25(x - 1) km.

    ∴ 20x + 25(x - 1) = 110

    ⟹ 45x = 135

    x = 3.

    So, they meet at 10 a.m.
