Mr. Oakley, my wood shop teachger is kind of strange. He has a 12 inch strip of wood with only four marks in it that he uses as a ruler. Yesterday, I asked him about it. "What good is a ruler you use uf ut only has 4 marks on it? There are some lengths you can't measure!" "Nonsense, I have placed them in such a way that I can measure any whole number length from 1 to 12 inches between the marks;" "I will get you started on your one. One of the marks is one inch from the end."
Where should I place the other 3?
