Mei and Anju are sitting next to each other on different horses on a carousel. Mei’s horse is 3 meters from the center of the carousel. Anju’s horse is 2 meters from the center. After one rotation of the carousel, how many more meters has Mei traveled than Anju?

In one rotation, each horse travels one circle’s circumference, which is 2π times its distance from the center. Mei travels 2π × 3 = 6π meters, while Anju travels 2π × 2 = 4π meters. The difference is 6π − 4π = 2π meters, so the answer is A, 2π more meters.
