Question

A train 200 metres long running at 36 km/h takes 55 seconds to pass a bridge . What is the length of the bridge .​

Answer 1

Answer:

350 m. Length of bridge = 350 metres.

Step-by-step explanation:

Distance covered by train at 36 kmph in 55 seconds is

=36kmph×55second(distance=time×speed)

=36×518m/s×55second

=550 metre

∴550 metre = total distance

Hence,

550 metre=length of the trains +length of bridge

550 metre=200m+length of bridge

Length of bridge = 350 metres.
