Question: Napoleon is practicing his tetherball skills. Every time he hits the ball, it takes 6 seconds to swing back around the pole. How many times can Napoleon hit the ball in 45 seconds?
Answer: 8 times
Solution: If we count up by 6s from 0, we find each second mark when Napoleon hits the ball. Napoleon hits the ball at 0, 6, 12, 18, 24, 30, 36, and 42 seconds. The next time he would hit the ball would be at 48 seconds, which is more than 45 seconds. So, if we count up the times that Napoleon hits the ball, we find that he can hit it 8 times.
