Question

An electric train is moving with a velocity of 120 km/h, how much distance will it move in 30 s?

Answer 1

Explanation:

Velocity= 120

time = 30s

distance= Velocity/ time

answer will be 120/30 i.e. 40

Answer 2

Explanation:

velocity=120km/hr=120×5/18=33.33m/s

time=30

dist.=velocity×time

=33.33×30

=1000m

=1km

So,the distance or displacement travelled by the electric train moving with a velocity of 120km/hr in 30sec is 1km
