Question

A electric train is moving with a velocity of 120Km/ hr. How much distance will it move in 30secomd?​

Answer 1

V = 120 km/hr

= 120 * 5/18

= 100/3 m/s

t = 30s

d = ?

d = Vt

= 100/3 * 30

= 1000m

= 1 km

Or

v=120 km/h

=120*1000\3600

=120000m/3600s

t=30 s

v=S/t

S=v*t

S=120000/3600*30

=1000m

Hope it helps(^o^)
