The question should be, "How long does it take Buster to clean the kitchen by himself?"
                     RATE           TIME          AMOUNT OF KITCHEN

Dave                1/12            12               1

Buster              1/x             x                1

Combined           1/(5&1/2)        5&1/2            1
Dave & Buster
