To get out of the railway station near Quiz Master Shop Towers there is an escalator that carries passengers from the platform to road level in 30 seconds. Most people simply stand there and travel up without walking, but it is quicker if you walk as well, of course.
One of our colleagues always walks and, being so minded, timed the ascent. Walking reduced the journey time from 30 seconds to 12 seconds.
Unfortunately the escalator was broken yesterday and everyone had to walk up the stationary steps.
How long did our colleague take to walk up the static escalator?
