Question

find the distance in metre travelled by a train in 20 minutes when travelling with a speed of 72 kilometre per hour ​

Answer 1

Answer:

Time taken my train = 20 minutes

= 1200 seconds

Speed of the train = 72 km/h

= 72/3.6 m/s

= 20 m/s

We know,

Speed = distance / time

Distance = speed x time

Distance = 20 x 1200

Distance = 24000m

Answer 2

Given,

Speed,v=72km/h

Time,t=20 minutes

=(20/60)hr

=(1/3)hr

Distance,s=?

We know that, v=s/t

i,e, s=v*t

s=72*(1/3)

=72/3

=24km

Therefore, the distance travelled is 24km
