Q: Suppose you want to calculate how long an escalator is. You have two times: the time it takes you to ascend the escalator while standing still, and the time it takes you to ascend the escalator while walking at a speed of x meters/second. Q: Some easy probability question on bounding the event of rain on a second day if it rained on the first. I'm sure there's someone else on here who gave a more detailed account. A follow-up required knowledge about union-bound if I recall correctly.
Person A walks up an escalator at 2 steps/second. Person B walks up an escalator at 3 steps/second. Person B gets on the escalator 5 seconds after A and arrives at the top X seconds after A. (I forgot the exact value of X) If the escalator is moving at 1 step/second, how many steps are visible on the escalator at a single point in time?
