A 400 m long train takes 36 seconds to cross a man walking at 20 km per hour in the direction opposite to that of the train. What is the speed of the train?

Answers

Answered by anu2720

Relative speed of train

=
400/36m/s =400/36×18/5=40km/h

Relative Speed of train = Speed of train + Speed of man

=> 40 = Speed of train + 20

Therefore, Speed of train = 40 - 20 = 20 km/h
