So here you have the graph of the velocity of an object, and we're asked to, in part a, give the distance travel during the first one second.
00:09
It seems like you got that right.
00:10
It's one -half base times height for this little triangle.
00:13
Base and height are both one, so it's just one over two.
00:16
Then for part b, we're asked to give the distance traveled between one and nine seconds.
00:21
So we'd want to consider this as areas a, b, and c.
00:26
So the distance traveled, now, given the fact that there's a difference between the total displacement and the distance traveled, going to...
00:40
All right, pardon me.
00:42
So, for the area of a, it's still one -half base times height.
00:47
Now, the base would be three rather than one, so that would just be three over two for a...
