So you want to know how to best express where an elevator is, if so, here's the answer:

So first we see that Elevator 1 went from ground level, to +20 feet, so we could say that Elevator 1 is 20 feet above ground level.

Then we see that Elevator 2 went from ground level, to -30 feet, so we could say that Elevator 2 is 30 feet below ground level.

So the answer is: Elevator 1 is 20 feet above ground level, and Elevator 2 is 30 feet below ground level.

Hope this helped! c:
