Kendall can wash the golf carts at the country club in 4 hours. If Benny helps him, they can get the job done in 2 hours. How long will it take Benny to do the job by himself?

I would say 4 hours because if Benny HELPS Kendall then the job will be done quicker but if he isn’t the helper and he does it alone he will take longer because the two working on it together divides the work load and if he is to do it himself he is gonna take longer

Ithink if ur looking for a ratio it would be 12: 3
