Let the man be of negligible dimension.
Then the only distance the the train has to cover is 28m.The speed of train is 42km/hr,so convert the km into m by multiplying it by 1000 and. Converts the hour in seconds by dividing the total equation by 3600.As time taken =distance by speed so divide 28m by 42000/3600 and the ans is 2.4 sec
