I need a thread to keep me occupied and need to keep my brain kind of active so basically it goes like this, you answer the post above before posting your own i shall start. You can paddle your canoe seven miles per hour through any placid lake. The stream flows at three miles per hour. The moment you start to paddle up stream a fisherman looses one of his bobbers in the water fourteen miles up stream of you. How many hours does it take for you and the bobber to meet?
