An odometer registers the number of miles traveled by counting the number of times a tire turns. Adam's odometer is set for 18" diameter tires, but he decided to put 16" diameter tires on his bike. After a long ride, Adam's odometer said that he traveled about 47 miles. how far did Adam really travel ?
