You’ve been on a cruise for two days when there’s an accident that forces everyone on board to abandon ship. During the evacuation, one of the boats is damaged, leaving it with a hole that fills it with water. You figure that with 10 people in the boat, you can keep the boat afloat by having nine people scoop the filling water out by hand for 10 minutes while the 10th person rests. After that person’s 10-minute rest, he or she will get back to work while another person rests, and so on. This should keep the boat from sinking long enough for a rescue team to find you as long as it happens within five hours. You’re taking your first brake when you notice your best friend in a sound lifeboat with only nine people in it and he beckons you to swim over and join them so you won’t have to keep bailing out water. If you leave the people in the sinking boat, they will only be able to stay afloat for two hours instead of five, decreasing their chance of being rescued, but securing yours. What do you do?
Stay in your boat and hope that you are all rescued in five hours time, before the boat sinks and you all drown.
