Question

A big city playground has 16 floors. Each floor is connected to another by various mechanical devices. Any even numbered floor has an escalator up to the next even numbered floor. Every odd numbered floor has a slide down to the next odd numbered floor. Several other floors (1,2,3,5,8,13) have an up and down chute that will take you to any other chute floor above and below. How could someone get from the 11th floor to the 12th floor?

Answer 1

Explanation:

From the 11th floor, someone can slide down to 9th, then 7th, then to 5th. At the 5th floor, they take the chute up to 8th floor and go up the escalator to 10th and then to 12th.
