Directions: Evaluate or solve the following word problem.

Every year at the fair, Gianna and Mila can’t agree upon which ride to experience. After 2 hours of arguing, they eventually agree upon enjoying separate experiences. Mila decides to experience the 125 foot plunge of the Drop Elevator which finishes its drop sequence in 6 minutes. On the other hand Gianna will expend her remaining 4 tickets on the Coaster of Curses which finishes its quarter mile track in 9 minutes. If both girls continuously rode each ride, then in how many minutes would they both get off of the ride at the same time? How many times would each have ridden their respective rides?
