document.write( "First tap fills  \"1%2F60\"  of the tank volume per minute.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The second tap fills  \"1%2F25\"  of the tank volume per minute.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The third tap fills  \"1%2F15\"  of the tank volume per minute.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Working together, the three taps fill  \"1%2F60+%2B+1%2F25+%2B+1%2F15\" = \"5%2F300+%2B+12%2F300+%2B+20%2F300\" = \"%285%2B12%2B20%29%2F300\" = \"37%2F300\" of the tank volume per minute.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the filling process will require \"300%2F37\" = 8.11 minutes, if all three taps run at the same time.\r\n" );
