Problem

A jogger moves along a straight east–west track as follows: 200 m200\,\text{m} east in 2 min2\,\text{min}, followed by 100 m100\,\text{m} east in 1 min1\,\text{min}, and finally 150 m150\,\text{m} west in 2 min2\,\text{min}. (a) Determine the jogger’s average speed for the whole run. (b) Determine the jogger’s average velocity (magnitude and direction) for the whole run.
