Question

A train travelling at 20 km per hour takes 30 second to pass a pole find the length of the train

Answer 1

Answer:

s=d/t,d=st.20*30=600

Answer 2

Answer:

Trains length is 166.67 m

Explanation:

From the question we know that the speed of the train is given as 20 km/h which is 20 × (5/18) = 100/18 m/s.

And the time which is taken by the train for passing a pole = 30 seconds.

We also know that the trained must have passed the pole completely in 30 seconds. So, the length of the train will be the distance that the train covered in 30 seconds with the speed of 20km/hr.

So, the length of the train is = speed × time.

= 100/18 × 30.

= 166.67 m.
