Eighteen friends are at Fun Park. There are many rides at the park. The Tilty Whirl has cars that holds two people each. The Ferris Wheel has cars that hold four people each. The Roller Coaster has cars that hold six people each. The Water Log has cars that hold five people each. All cars must be filled with people before a ride starts. The friends do not want to share a ride with anyone they do not know. Which rides can the friends ride?
18 = 2*3*3
