Is that it? Or is that on the long side? If I imagine a 20-second count in my head, it seems on the long side. But if I can see the elevator light up the floors, maybe it's not so long. What do you guys think?
Christy actually revealed a lot of interesting tidbits about elevators and how they work and solve problems with math. Like how to tweak elevator speed to accomodate more rides, how many people squeeze into elevators in Western Countries versus Asia and how she uses a computer simulation program that replays elevator decision making (like a video game!) to analyze what to do.
