Escalator. While riding one of the escalators in the London Underground, I noticed that if I walked down 26 steps, I would reach the platform in 30 seconds. However, if I walked down 34 steps, the entire descent would take 18 seconds. How many steps are there on the escalator? The time is measured from the moment the top step begins to descend until I step off the last step onto the platform.
