A man is wandering through the desert with a compass but without his map. He is out of water and needs to return to his starting position in order to survive. He estimates that he has traveled for 2 hours at a bearing of 250 degrees and 1 hour at a bearing of 170 degrees and his hiking pace has been approximately 2 mph for the whole time. How far must he travel to return to his starting spot? In what direction (bearing)? How long will it take to get back?
