A train takes 16 seconds to pass a pole and 24 seconds
to pass through a 200-meter-long tunnel. If the train overtakes a man running in the same direction in 24 seconds, with the train being faster than the man, find the man's speed.Solution
Let, The length of train= X Speed= distance/ time X/16= (X +200)/24 8x= 3200 X= 400 Let the speed of man= S m/s Speed of train = 400/16 = 25 m/s 400= (25-S)×24 100=150-6s S= 25/3 m/s = 30 kmph Answer: B
