Question

A train is running at 36 km/hr. If it crosses a pole in 15 seconds, find its length.

Answer 1

first convert 36km/hr in m/s
10m/s
s=d/t
10=d/15
d=150meters
so train length is also 150 m



if its true say yes

Answer 2

Given speed of the train=36 km/hr

                                                  =36*5/18

                                                   =10 m/sec

Given that a train crosses the pole in =15 sec

Then the length of the train=Speed*time

                                                 = 10*15

                                                  =150 m
