so question three. Ask for the displacement, magnitude of displacement and the distance of line. See, so you can see line. See starts a two meters, goes out to 10 meters back to eight and then out to 10 again. So to find the total distance traveled, we have to take into account all of these twists and turns. So it's going to be 2 to 10 which is eight meters plus the additional two meters back plus the two meters forwards again. And so it has a total distance traveled of 12 meters part B s for the magnitude of the displacement. So disregarding direction, just how much did the position change? It started at two meters and ended at 10. So no matter what it did in between, it changed its position by eight years. For part C. We want to know that direction as well for the overall displacement. And because this starts at two and ends at 10 it's over. All this placement is eight meters in the positive direction
