You walk upwards on an escalator, with a speed of 1 step per second. After 50 steps you are at the end. You turn around and run downwards with a speed of 5 steps per second. After 125 steps you are back at the beginning of the escalator.
How many steps do you need if the escalator stands still?
For something somewhat related please see "Walking down an escalator"
The escalator is 100 stairs and rises 1 step each second.
Ascending the escalator,
50 steps + (50/1) seconds of stair rises = 100.
Descending the escalator,
125 steps - (125/5) seconds of stair rises = 100.
200 steps will be taken to ascend and descend the
