60km is converted to 60000m and 1 hour to 3600sec, there for 60000/3600 answer to 16.66 and multiple to 9sec and answer is 149.999.

So, here, the full value as 150 metres.

Speed = 60 km/h = 60 * 5/18
= 50/3 m/s.
Time taken = 9 sec.
Length = speed * time = 50/3 * 9.
=150 m.

Here L = speed(m/s) x time(s).
= 150m.

So the pole been exposed to the train for 9 sec, in a speed of 60km/hr, which is equivalent to covering a distance equals speed (m/s) x time (s) = 150m.
