\r\n" );
document.write( "Their combined rate of work is  \"1%2F3\" + \"1%2F5\" = \"5%2F15+%2B+3%2F15\" = \"8%2F15\"  of the job per hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Therefore, the process will take  \"15%2F8\" hours = 1 \"7%2F8\" hours = 1 hour and 52.5 minutes.\r\n" );
