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 +90+ 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 +90+ m
---------------------------------------
Now the end of the train is at the start of the station,
so it needs to go another +90+ m
+90+%2B+90+%2B+90+=+270+ m length of travel
-------------------------------------
Convert +36+ km/hr = +36000+ m/hr
+t+=+270+%2F+36000+
+t+=.0075+ hrs
Convert to minutes
+.0075%2A60+=+.45+ min
Convert to seconds:
+.45%2A60+=+27+
The train takes 27 sec to pass through the station
