      Question

      There are two trains A and B. A start from point

      X at 7 AM towards point Y. Another train B starts at 9 AM from point X. If they meet at 11 AM and speed of A is 25 km/hr, while that of B is 44 km/hr. Find distance between X and Y.
      A 120 km Correct Answer Incorrect Answer
      B 160 km Correct Answer Incorrect Answer
      C 145 km Correct Answer Incorrect Answer
      D 188 km Correct Answer Incorrect Answer
      E 144 km Correct Answer Incorrect Answer

      Solution

      Speed of train A = 25 kmph
      Speed of train B = 44 kmph
      Time taken by train A to meet train B at 11 AM = 4 hrs
      Time taken by train B to meet train A at 11 AM = 2 hrs
      Distance travelled by train A = 4 × 25 = 100 km
      Distance travelled by train B = 2 × 44 = 88 km
      Therefore, total distance between X and Y = 100 + 88 = 188 km
