The 9 min Pasta Timer Puzzle
September 18, 2010 at 11:23 pm Leave a comment
Today I have to make dinner and have to boil some pasta for exactly 9 minutes. However, I only have two hourglasses. One of them measures 7 minutes and the other measures 4 minutes.
Can I use the hourglasses to time exactly 9 minutes?
