      Question

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

      same time and started travelling towards each other at speeds of 30 km/hr and 20 km/hr, respectively. At the time of their meeting, the faster train has travelled 200 km more than the slower train. Find the distance between the stations β€˜A and β€˜B’.
      A 1100 km Correct Answer Incorrect Answer
      B 1200 km Correct Answer Incorrect Answer
      C 1000 km Correct Answer Incorrect Answer
      D 1300 km Correct Answer Incorrect Answer

      Solution

      Let the distance travelled by slower train be β€˜x’ km So, distance travelled by faster train = β€˜x + 200’ km ATQ, (x/20) = {(x + 200)/30} Or, 30x = 20x + 4000 Or, 10x = 4000 So, x = 400 Total distance between station β€˜A’ and station β€˜B’ = (400 + 400 + 200) = 1000 km
