Answer 2

Answer:

GIVEN:

LENGTH OF TRAIN:400m

SPEED OF TRAIN:72km / h Or 20m / s

TIME TOOK IN CROSSING THE BRIDGE:1 min Or 60s

TO FIND:

LENGTH OF BRIDGE

SOLUTION:

let the length of bridge be x

the train takes the time 60 s

so the length covered by train in 60 s is

60×20=1200 m

but the train have length 400m

so there will be 400+400 at the end and start of bridge.

so, there will be subtraction of 800m

which is 1200-800=400m
