Question

an electric train is moving with a velocity of 120 km per hour how much distance will it move in 30 seconds

Answer 1

Hey dear ur answer☜☆☞⌐╦╦═─
Velocity v =120km/h
Time taken-30s=30/3600=1/120h
Distance covered in 1 h = 120 km

I.e. 60*60 seconds = 120*1000 m

Distance in 30 sec= (120000/3600 )* 30

= 1000 m or 1 km
Hope it help you⌐╦╦═─☜☆☞

Answer 2

Given :-

The train is moving with velocity =  120 km/h
 t= 30 s.
d = ?
We know that 1 hr = 3600 sec.
So now velocity,

$\frac{120 * 5}{18}$
= 600 /18
v= 100/3 .
We know that the distance d = v x t
d = $\frac{100}{3}$ × $30_{}$

d = 1000 m or 1 km.


Hence the distance covered by train in 30 sec is 1 km.


Hope it Helps.
