Recently, I decided to walk down an escalator of a tube station. I did some
quick calculation in my mind. I found that if I walk down twenty – six steps, I
require thirty seconds to reach the bottom. However, if I am able to step down
thirty – four stairs, I would only require eighteen seconds to get to the
bottom. If the time is measured from the moment the top step begins to descend
to the time I step off the last step at the bottom, can you tell me the height
of the stairway in steps.
