Question

A train 100m long running at 36 km per hour takes 25 seconds to pass a bridge what is the length of the bridge

Answer 1

X+100=36×5/18×25
=X=150m.

Answer 2

Answer:

150 m is the length of the bridge

Step-by-step explanation:

the speed of a train=36 km/h

time taken to pass a bridge = 25 seconds

length of the train =100 metres

distance = length of the bridge + length of the train

x+100m

distance =speed ×time

speed in m/s

36×5/18= 10 m/s

d= 10 ×25

250 m

length of the train + length of the bridge = total distance

total distance = x+100

250m = x+100 m

250-100=x

150 m= x

length of the bridge =150 m
