If it takes 15 minutes to load 3 racks of buns how many hours will it take to load 36 racks

It would take 3 hours. Hope this helps :)

If we divide 15 by 3, we see that it takes 5 minutes to load each rack. Multiply 36 times 5, and we get 180 minutes. The question wants hours, though, so we have to divide 180 minutes by 60 minutes (which is the same as one hour). Our answer is 3 hours.

What is the statement?
