Step-by-step explanation:
In 6 seconds, the train crosses a walking man
Distance covered in 6 secs. = the length of the train
Speed = length of the traintime=150 = 25 m/sec.
= 25×185 = 90 kmph
Since the train and the man are moving in opposite directions
relative speed = 90 kmph.
The man is walking at a speed of 6 kmph.
Speed if tge train = (90 - 6) = 84 kmph
