document.write( "The faucet fills {{1/15}}} of the bathtub volume each minute.\r\n" );
document.write( "\r\n" );
document.write( "The drain release   of the bathtub volume each minute.\r\n" );
document.write( "\r\n" );
document.write( "The net balance is  =  =  of the bathtub volume per minutes.\r\n" );
document.write( "\r\n" );
document.write( "Hence, it will take 60 minutes = 1 hour to fill the bathtub if both faucet and drain are turned on.\r\n" );
