14 Time(s)

Answer 3

there are twice of 3 units when it wasn't moving, and the rest of the time it was in motion (either up or down).

Answer 4

I supposed (s) stands for seconds, Therefor 14 seconds.

Answer 5

but it is asking for motion up and down, and it was not going up or down, between 2 and 5, and between 8 and 11.

Answer 9

you are asked to find the entire time when the elevator is moving up or down. you know that. I told you that I found 2 time-frames of times , 3 units/seconds each, when the elevator is not moving.
