Question

an electric train is moment with a velocity of 120km/h. how much it move in 30sec​

Answer 1

Explanation:

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

Answer 2

• Speed of train =120km/h
• Time=30s

Convert speed to m/s

$\\ \sf\longmapsto 120\times \dfrac{5}{18}$

$\\ \sf\longmapsto \dfrac{600}{18}$

$\\ \sf\longmapsto 33.3m/s$

We know

$\boxed{\sf Speed=\dfrac{Distance}{Time}}$

$\\ \sf\longmapsto Distance=Speed\times Time$

$\\ \sf\longmapsto Distance=33.3(30)$

$\\ \sf\longmapsto Distance=999m$
