Imagine which you're trapped in circular room with three doors symmetrically placed around perimeter. You're told by a mysterious voice that one doorleads to the outside after 2-h trip through a maze. But, the other two doors lead to mazes that terminate back in the room after a 2-h trip at which time you're unable to tell through which dooe you exited or entered. Determine the average time for escape to the outside? Can you guess the answer ahead of time? If not, you can provide a physical explanation for the answer you calculate?
