Answer:If you stay on the original boat, you will help keep it afloat for the full 5 hours, maximizing the chances of rescue for all 15 people. However, if you leave to join your friend’s boat, you will ensure your own safety and comfort, but you will significantly reduce the chances of the remaining 14 people being rescued, as their boat will only stay afloat for 2 hours. Your decision should reflect whether you prioritize your own safety or the well-being of the others on the sinking boat.
