Question

train travel 36 kilometre for an hour cross 14 second to cross a hundred metre bridge what is the length of the train​

Answer 1

Answer:

Speed if train , v = 36 km/h = 10 m/s

Let x metre be the length of train.

Total distance to be travelled by train to cross the bridge

=(x+100)m

As distance = speed × time

∴(x+100)=10×14 or x=40m

Answer 2

Answer:

Total distance = bridge length plus length of train

velocity is 36kmph which is 10m/s

distance = speed X time

100+ length = 10x 14

length = 140-100 = 40m
