A truck moves 70m east, then moves 120m west, and finally moves east again a distance of 90 m. If east is chosen as the positive direction, what is the trucks resultant displacement?

    The truck ends up 160 miles east and 120 miles north of where it started. Perform a vector addition. It looks like you have a 3-4-5 right triangle, so the answer might be obvious.
