same direction with a certain speed, in 50 seconds. If the same train can cross a tree in 20 seconds with the same speed, then find the speed of the man.Solution
Speed of train = 500/20 = 25 m/sec Let the speed of the man be βsβ m/sec Relative speed of the train = (25 β s) m/sec According to the question, (25 β s) = 500/50 Or, s = 25 β 10 = 15 Therefore, speed of the man = 15 m/sec
