I'm assuming the drain is left 1/2 open
\n" ); document.write( "The drain being 1/2 open, means the tank
\n" ); document.write( "will take twice as long to drain, or 22 hrs
\n" ); document.write( "-----------------------------------
\n" ); document.write( "Let \"+t+\" = time in hrs to fill the tank
\n" ); document.write( "\"+1%2F9+-+1%2F22+=+1%2Ft+\"
\n" ); document.write( "Multiply both sides by \"+9%2A22+=+198+\"
\n" ); document.write( "\"+22+-+9+=+198%2Ft+\"
\n" ); document.write( "\"+13+=+198%2Ft+\"
\n" ); document.write( "\"+t+=+198%2F13+\"
\n" ); document.write( "\"+t+=+15.231\"
\n" ); document.write( "It will take 15.231 hrs to fill the tank
\n" ); document.write( "---------------
\n" ); document.write( "check:
\n" ); document.write( "\"+1%2F9+-+1%2F22+=+1%2Ft+\"
\n" ); document.write( "\"+1%2F9+-+1%2F22+=+1%2F15.231+\"
\n" ); document.write( "\"+.111+-+.0455+=+.06565+\"
\n" ); document.write( "\"+.0656+=+.06565+\"
\n" ); document.write( "close enough
