Question

an electric train is moving with a velocity of 120 km /hr . how much distance will it cover in 30 seconds

Answer 1

The velocity of train = 120 km/hr = 120×5/18m/s
= 100/3 m/s

Time Taken = 30 seconds.

We , know that formula for distance →

Velocity × Time

= 100/3 × 30

= 100 × 10

= 1000m

= 1km

Answer → Train will cover 1km in 30seconds.

Answer 2

Distance covered by the train in 1 hour = 120km
Distance covered by it in 1 minute = 120/60
