So like always, pause this video and see if you can work through it on your own. So now let's tackle this together. So the key question is what is the total distance the particle has traveled between t equals two and t equals six? So we just care what happens between those points. We don't care that the particle's distance from the starting point was five meters at t equals two. So this right over here is actually unnecessary information. So the first thing that you might want to think about is well maybe distance is just the integral of the velocity function.
