2. The World Paper Clip Blowing Championships were held recently. In the competition, contestants were required to blow a paper clip along a polished wooden floor. Each contestant was given 3 turns to blow their paper clip and the distance the paper clip moved each time was recorded. The person who blew their paper clip the furthest when the 3 turns were added together was the winner. Can you work out who the winner was?
