Max and his dog Molly set out for a walk. Max walked up the road and then back down again, completing a six mile round trip. Molly, being an old dog, walked at half Max’s speed. When Max reached the end of the road, he turned around and walked back to the starting point, at his original speed.
Part way back he met Molly, who then turned around and followed Max home, still maintaining her original speed.
