20. 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.
