Use the stairs! (Posted on 2008-09-12) Difficulty: 2 of 5
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.

The Question:
How many steps do you need if the escalator stands still?

For something somewhat related please see "Walking down an escalator".
