You have just purchased three things from the market: a wolf, a duck, and a bag of seeds. To get back home you must travel across a river in a small boat. You are only allowed to have one item with you on your boat at any time. You cannot leave the wolf with the duck, because the wolf will eat the duck. You cannot leave the duck alone with the bag of seeds, because the duck will eat the seeds. [This also applies on the other side of the river]
How many trips on the boat must you take to be able to get the wolf, the duck, and the bag of seeds across to the other side of the river safely?
Enjoy!
