Fast and Slow Running train



           An express train leaves Calcutta for Bombay at the same time as a passenger train leaves Bombay for Calcutta. The express travels at the speed of 60 kilometres per hour and the slow train at the rate of 30 kilometres per hour. Which is further form Calcutta when they meet?

Answer:    No ! The answer is not the express. If we do not take into consideration the length of the train, then slow train and express are the same distance from Calcutta when they meet.
