document.write( "A constant rate 0.2 liter per second means 1 (one) liter in 5 seconds.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the time to empty this tank is 360*5 = 1800 seconds.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "To get minutes, divide 1800 seconds by 60 seconds, because 1 minute is 60 seconds.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  1800/60 = 180/6 = 30 minutes.\r\n" );
