Answer:
Train covers a distance of 1 km in 30 seconds.
Explanation:
Given,
Velocity of train is 120 km / h.
It means : Train covers a distance of 120 km in 1 hour.
Thus,
= > Distance covered in 1 hour = 120 km
= > Distance covered in 60 minutes = 120 km
= > Distance covered in ( 60 x 60 sec ) = 120 km
= > Distance covered in 30 sec = 30 x ( 120 km ) / ( 60 x 60 )
= > Distance covered in 30 sec = 3600 / 3600 km
= > Distance covered in 30 sec = 1 km
Hence the train covers a distance of 1 km in 30 seconds.

why would u write such a long answer
Velocity = distance / time
= > 120 km / h = distance / 30 sec
= > ( 120 km ) / ( 60 x 60 sec ) x 30 sec = distance
= > 1 km = distance
