\r\n" );
document.write( "The rate of two hoses working simultaneously (1 + 1)  is  of the pool volume per hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the rate of one (each, single) hose is  of the pool volume per hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the rate of 3 hoses working simultaneously (1 + 1 + 1) is  = .\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Therefore, the three hoses will take 16 hours to drain the pool, working simultaneously.\r\n" );
