Utitilies and houses can be arranged in any order. Each house must have a utility line from each of the 3 utilities coming into the house and these lines can not cross above or below the ground. More than 50 years ago, I had an elementry teacher asked this riddle and I (and many others) have tried to solve this problem without success. No matter how I lay out the houses and utilities, I can get 2 houses with 3 utilitiy lines, but the third house will only have 2 utilities. I am under the impression that it can not be done. I would like someone to confirm that it is impossible to solve and hopefully tell me why it is not possible. Thank you
