Question

A train is running at a speed of 36 km/hr. It crosses a pole in 20 seconds.
Its length is-​

Answer 1

Answer:

distance=speed /time

speed =36km/hr = 10m/sec.

distance = 10/20

=1/2 meter

Answer 2

Answer:

200m

Explanation:

Given :

• Speed => 36m/hr=36*1000/60*60

=>10m/s

• Time => 20seconds

To Find :

• Distance = ?

Solution :

$\sf{} We\; know\; Speed=\dfrac{Distance}{Time}$

Put their given values and solve it

$\sf{}\rightarrow 10=\dfrac{Distance}{20}$

$\sf{}\rightarrow 10\times20=Distance$

$\sf{}\rightarrow Distance= 200$

Therefore,total distance is 200m
