And this problem, we have two planes that start from la international airport, and they fly in opposite directions.
00:06
The second plane starts a half hour after the first plane, but its speed is 60 kilometers per hour faster.
00:12
So we're saying now that airplane x, so one of them leaves going to the left, and the other one leaves going through the right.
00:21
So we're going to say, here's the starting position, and they go this way, and the element goes that way.
00:27
And after, i'm going to leave the arrows off, actually.
00:29
I'm just going to say it goes this way.
00:32
Now we know that this total distance is 200 or 2 ,890.
00:37
So the one that's going to the left, we'll say that that's the first one.
00:40
It's traveling at a certain speed x, a certain speed per hour.
00:45
So after two hours it goes 2x distance.
00:49
Now the second one, its speed, is x plus 60...
