It has always been speculated that the left queue of most attractions at Walt Disney World tend to progress faster than the right queue. On the new Rock’N’Roll Coaster, cast members allow 50 guests into the left and 10 guests into the right queue immediately at park opening. Every minute after that 10 guests are added to the left queue and 12 guests are added to the right queue.
How long will it take to move the same number of guests to move through both queues?
How many guests will go through the left and right queues after one hour? How many guests will go through the left and right queues after a twelve-hour day?
