Distance = speed*time.
60*5/18*9,
60*5/2,
300/2 = 150.
60*5/18*9,
60*5/2,
300/2 = 150.

Speed = Ditance/Time.
Distance = Speed * Time.
Or lenght = Speed * Time .
=( 60 *5/18) * 9,
= 50/3 * 9,
= 50 * 3 ,
= 150 meter.

We calculated the train length with reference to the pole. But what about the length of the pole. Doesn't it come to picture here?
Please, anyone, clarify it.
