Question

Two trains of lengths 200m and 250m respectively are running in opposite directions on parallel tracks.If their speed be 45km/h and 50km/h respectively,in what time will they cross each other?​

Answer 1

Answer:

hii hope this helps

Step-by-step explanation:

Length of 1st train=200m

Speed of 1st train=45 km/h

=45×5/18=12.5 m/s

Length of 2nd train=250 m

Speed of 2nd train=50km/h=13.88 m/s=14 m/s

Here question Saying time taken to pass Both trains.Means train has now meet and We have to find after how many seconds both Train will be on passing each.

Then total Length=200+250=450 m

Total speed=12.5+14=26.5 m/s

Time=Length/speed

Time=450/26.5

Time=13.98 second

Almost=14 seconds
