Answer 1

Answer:

When a train has to cross a stationary object, it has to cover a distance equal to its own length. 

In this case the distance covered 

= 150 m = 3/20 km 

speed of train = 50 km/h 

50 km is covered in = 60 minutes 

1 km is covered in = 60/50 minutes 

203 km is covered in = 60/50×3/20 or 9/50 minutes 

= 9/50×60  so answer is 10.8 second .
