Dysfunctional Crossing (Posted on 2005-09-26) Difficulty: 3 of 5
There are 8 people that need to cross a river. The water is too deep and fast to walk or swim across, and the only transportation device available is a raft. The raft can only be operated by adults, cannot float across the river on its own, and can carry at most two people.

The 8 people are a juvenile delinquent, her jailer, and a dysfunctional family of six: mother, father, two sons, and two daughters. To be clear, the only adults are the jailer, the mother, and the father.

Unfortunately some people fight with each other:

  • The juvenile delinquent will fight with anybody if her jailer is not present.
  • The father fights with either daughter if the mother is not present to mediate.
  • The mother fights with either son if the father is not present to mediate.
  • How can these 8 people cross the river without any fights? How many trips on the raft did it take?
