This is a five by five triangle. So five times five is 25, times 1 1⁄2, remember, area of a triangle's 1 1⁄2 base times height. So this is going to be 12.5, and let's see, this is going to be meters per second times seconds, so 12.5 meters. So that's the change in position for that particle over the first five seconds. Wherever it started, it's now going to be 12.5 meters to the right of it, assuming that positive is to the right. Now what about over the first 10 seconds? Now this gets interesting, and I encourage you to pause your video and think about it.
