Question

a 600 m long train is crossing a bridge of 1200 m with a velocity of 20 m/s . Te taken by the train to cross the bridge completely is​

Answer 1

Answer:

time = distance / Speed

d = 1200-600

=600

time=600/20

so the time taken = 30seconds

Answer 2

Answer:

See if we divide 1200 by 600 then we get

2

then, multiply velocity by 2

So, 20*2=40

Then the train take time of 40 second
