Question

Train 120 metre long passes a tree in 5 seconds how long will it take to cross a railway platform 180 long

Answer 1

Answer:

Since the length of the tree is negligible, so distance in first case is taken as the length of the train.

Speed = Distance / Time

= 120/5

= 24 m/s

Now ,

Distance = ( 120 + 180 ) = 300 m

Speed = 24 m/s

Time = Distance / Speed

= 300 / 24

= 25/2

= 12.5 seconds
