Question

find the time taken by the train 150m long . running at 60 km/hr . in crossing a man standing on the plateform.

Answer 1

Speed = 60 km/hr = 60* 5/18 m/sec

                              = 50/3

Time = distance/speed = 150/50/3

                                        = 30 sec

Answer 2

Answer:

time 60kmph=60×5/18

speed =d/t

=150/(300/18)

150×(18/300)

=18/2

=9
