a swimming pool is empty.
\n" ); document.write( " at 1:00pm a hose is turned on and begins to deliver 5 gallons per minute into swimming pool.
\n" ); document.write( "thirty minutes later a second hose is turned on and pours 7 gallons per minute into the pool.
\n" ); document.write( " at what time will there be 1710 gallons of water in the pool.
\n" ); document.write( ":
\n" ); document.write( "Let t = number minutes that both hose are on (12 gal/min starting 1:30)
\n" ); document.write( "Find the number of minutes to fill the pool
\n" ); document.write( ":
\n" ); document.write( "(5*30)+12t = 1710
\n" ); document.write( "150 + 12t = 1710
\n" ); document.write( "12t = 1710 - 150
\n" ); document.write( "12t = 1560
\n" ); document.write( "t = 1560/12
\n" ); document.write( "t = 130 minutes from 1:30 pm
\n" ); document.write( "therefore
\n" ); document.write( "1:30 + 2:10 = 3:40 pm will have 1710 gal in the pool
\n" ); document.write( " \n" ); document.write( "
\n" );
