Question
1700 metres long train crosses a man who is moving in
the same direction with a certain speed, in 20 seconds. If the same train can cross a tree in 17 seconds with the same speed, then find the speed of the man.Solution
Speed of train = 1700/17 = 100 m/sec Let the speed of the man be ‘s’ m/sec Relative speed of the train = (100 – s) m/sec According to the question, (100 – s) = 1700/20 Or, s = 100 – 85 = 15 Therefore, speed of the man = 15 m/sec
