I would probably graph these two elevators.
00:03
So one elevator starts at 16 and goes up as time goes on and the other one starts at 12 and goes down as time goes on.
00:20
So that would be elevator b.
00:23
So how do i answer the first question? i'll just number it 1.
00:29
At this time then you're plugging in 0 to, well, let me call it h equals 0.
00:36
And so that's why elevator a is at 16 meters and then h equals 0 for this other one would be elevator b is at 12 meters.
01:03
So then the fact is one's going up and one's going down.
01:07
So in the next question, they are not going to pass each other.
01:12
So they are not going towards each other.
01:20
So therefore we can't, like no, we can't figure out those heights...
