A pipe can fill a tank in 3 hours if the drain is open. If the

pipe runs with the drain open for 1 hour and the drain is

then closed, the tank will be filled in 40 minutes more.

How long does it take the pipe to fill the tank if the drain

is closed?

I wasn't able to parse your question, but the HE.NET team is hard at work making me smarter.
