It takes 2 hours for 2 cleaners to clean 2 rooms, so it takes 1 hour for 1 cleaner to clean 1 room. If we have 5 cleaners, then it will take 5 hours for them to clean 5 rooms.
However, this is just a theoretical calculation. In reality, the cleaning time may vary depending on the size and complexity of the rooms, as well as the experience and efficiency of the cleaners.
