      Question

      Two trains started from stations β€˜A’ and β€˜B’ at

      same time and started travelling towards each other at speeds of 40 km/hr and 30 km/hr, respectively. At the time of their meeting, the faster train has travelled 100 km more than the slower train. Find the distance between the stations β€˜A and β€˜B’.
      A 720 km Correct Answer Incorrect Answer
      B 600 km Correct Answer Incorrect Answer
      C 700 km Correct Answer Incorrect Answer
      D 750 km Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Let the distance travelled by slower train be β€˜x’ km So, distance travelled by faster train = β€˜x + 100’ km ATQ, (x/30) = {(x + 100)/40} Or, 40x = 30x + 3000 Or, 10x = 3000 So, x = 300 Total distance between station β€˜A’ and station β€˜B’ = (300 + 300 + 100) = 700 km
