You can put this solution on YOUR website!
The rate of filling is:
+10%2F25+ liters/sec
---------------------
+40000+=+%28+10%2F25+%29%2At+
where +t+ is in seconds
+t+=+%2825%2F10%29%2A40000+
+t+=+100000+ sec
[ sec ] x [ min/sec ] = [ min ]
+100000%2A%281%2F60%29+=+t%5Bmin%5D+
+t%5Bmin%5D+=+1666.667+
To the nearest minute it will take
1667 minutes to fill the 40KL pool
---------------------
Since +27%2A60+=+1620+ and
+1667+-+1620+=+47+,
It will take 27 hrs 47 min
( if you want it in hrs too )
