Question

An electric train is moving with velocity of 120km/hr. how much distance will it cover in 30sec? ​

Answer 1

Answer:

Velocity = 120 km/h × 5/18 = 100/3 m/sec

time= 30 sec

distance= v × t

= 100/3 × 30

= 1000 m

so distance or displacement travelled by the electric train moving with velocity 120km/h in 30 sec is 1000 m.

Answer 2

given:

velocity = 120 km/ hr. ~ 12000 m / s

time = 30

$v = \frac{d}{t} \\ 12000 = \frac{d}{30}$

d = 360,000 m/s

hope it help ❣
