document.write( "Both hoses fill  \"1%2F42\"  of the pond volume per minute.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "One hose fills  \"1%2F91\"  of the pond volume per minute.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the second hose  fills  \"1%2F42\" - \"1%2F91\" = \"%2891-42%29%2F%2842%2A91%29\" = \"49%2F%2842%2A91%29\" = \"1%2F%286%2A13%29\" = \"1%2F78\"  of the pond volume per minute.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, it will take 78 minutes for the second hose to fill the pond.\r\n" );
