Answered by samhazard10

since speed = d/t

120/60=2

2km/min

2/2=1

1km per 30 seconds

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.

samhazard10: why would u write such a long answer

abhi569: We know,
Velocity = distance / time
= > 120 km / h = distance / 30 sec
= > ( 120 km ) / ( 60 x 60 sec ) x 30 sec = distance
= > 1 km = distance

abhi569: satisfying you ?

samhazard10: I wrote the answer

abhi569: it's written "step-by-step-explanation", I am just follow that sentence

samhazard10: Oh ok

samhazard10: I mean u r genius so it's fine

samhazard10: this was my first ever answer
