Want to find out how many steps are visible in an escalator. To this was done the following: two people began climbing an escalator together, one going one step at a time while the other climbed two . On top the first person counted 21 steps while the other 28. With this data it was possible to answer the question. How many steps are visible on that escalator? (Note: escalator is operating).

The person who was skipping every other step took more total steps than the person who wasn't? Were they going up a down escalator?
