Two workers, Alice and Bob, are assigned to clean a large office building. Alice can clean the
entire building in 6 hours, and Bob can clean the same building in 8 hours. They work together to
clean the building, but after working together for 2 hours, Alice is called away to another task.
How many more hours will it take Bob to finish cleaning the building by himself?
