Talk:Puzzles/Non-scientific puzzles/Boy, Girl, and a Dog

Answer: Anywhere between 0km and 1km? If the boy is 1km from the girl, the girl facing the boy, the boy facing away, and the dog in between, the girl walks backwards at 4km/h, the boy walks backwards at 5km/h and the dog runs backwards back and forth between the boy and girl with 10km/h, won't they all meet at a point in an hour, no matter where in between the dog starts? (With the dog getting a bit dizzy from turning around an infinite number of times?) كсηפ Cyp 16:01, 28 August 2005 (UTC)
