The time required to fill a pool with a water hose is 30 hours. Using a pump the pool can be filled in 10 hours. How long will it take to fill the pool using a pump and 2 hoses?
\n" ); document.write( ";
\n" ); document.write( "Let t = time required when two hoses and a pump are used
\n" ); document.write( "Let full pool = 1
\n" ); document.write( ":
\n" ); document.write( "\"%282t%29%2F30\" + \"t%2F10\" = 1
\n" ); document.write( ";
\n" ); document.write( "In the pool problem above how long would it take to fill the pool if the drain, which could drain the pool in 15 hours, is left open?
\n" ); document.write( ":
\n" ); document.write( "Same thing but subtract for the drain
\n" ); document.write( "\"%282t%29%2F30\" + \"t%2F10\" - \"t%2F15\"= 1\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
