Imagine that the head of the train is
just entering the station.
---------------------
When the head reaches the end of the station,
the train has traveled m
---------------------------
When the middle of the train, which is at the
start of the station reaches the end of the
station, the train has traveled another m
---------------------------------------
Now the end of the train is at the start of the station,
so it needs to go another m
m length of travel
-------------------------------------
Convert km/hr = m/hr
hrs
Convert to minutes
min
Convert to seconds:
The train takes 27 sec to pass through the station
