Peter's work rate is \"1%2F40\" lawns per minute.
\n" ); document.write( "John's work rate is \"1%2F60\" lawns per minute.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The two if work simultaneously, then the combined rate is to sum the two separate rates.\r
\n" ); document.write( "\n" ); document.write( "\"%281%2F40%2B1%2F60%29%28lawns%2Fminutes%29\"\r
\n" ); document.write( "\n" ); document.write( "\"%283%2F3%29%281%2F40%29%2B%282%2F2%29%281%2F60%29\"\r
\n" ); document.write( "\n" ); document.write( "\"3%2F120%2B2%2F120\"\r
\n" ); document.write( "\n" ); document.write( "\"5%2F120\"\r
\n" ); document.write( "\n" ); document.write( "\"5%2F%2810%2A12%29\"\r
\n" ); document.write( "\n" ); document.write( "\"1%2F24\"\"lawns%2Fminutes\"
\n" ); document.write( "meaning they need 24 minutes to mow the lawn, working together.
