Ker's rate, \"1%2F6\"
\n" ); document.write( "Kan's rate, \"1%2Fx\"
\n" ); document.write( "Ker AND Kan, \"1%2F3\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"1%2F6%2B1%2Fx=1%2F3\"\r
\n" ); document.write( "\n" ); document.write( "-\r
\n" ); document.write( "\n" ); document.write( "\"6x%281%2F6%2B1%2Fx%29=6x%281%2F3%29\"\r
\n" ); document.write( "\n" ); document.write( "\"x%2B6=2x\"\r
\n" ); document.write( "\n" ); document.write( "\"x=6\"----------------Kan can also do the one job alone in 6 hours.
