Eleven girls are standing around a circle. A ball is thrown clockwise around the circle. The first girl, Ami, starts with the ball, skips the next three girls and throws to the
fifth girl, who then skips the next three girls and throws the ball to the ninth girl. If
the throwing pattern continues, including Ami's initial throw, how many total throws are
necessary for the ball to return to Ami?
