A man and a goat are on one side of the river. They have a boat which can carry both of them at the same time. How do they get to the other side?
The man and the goat can both get to the other side of the river together using the boat since the boat can carry both of them at the same time. Here's how they can do it:
The man and the goat both get into the boat.
The man rows the boat, carrying himself and the goat across the river.
They both disembark on the other side.
Since the boat can carry both the man and the goat simultaneously, there are no restrictions preventing them from crossing together in one trip.
