A train speeds past a pole in 15 seconds and a platform 100
m long in 25 seconds. Its length is

Answer Posted / binesh nambiar c

Length of the platform
is 100m. So the train
needs to traval 200m
to cover the station
(when the train travals
100m its fully inside
the station)

it took 25s to cover
this distance. So speed
of train is
200m/25s=8m/s

consider pole dont
have width or consider
it as a point

train took 15 second to
cover that

so length of train=8m/
s*15s=120m
