Problem

A person walks 60 m60\,\text{m} east in 1 min1\,\text{min} and then 80 m80\,\text{m} north in the next 2 min2\,\text{min}. What is the magnitude of the person's average velocity for the entire 3 min3\,\text{min} interval? (a) 0.78 m s−10.78\,\text{m s}^{-1} (b) 0.83 m s−10.83\,\text{m s}^{-1} (c) 0.56 m s−10.56\,\text{m s}^{-1} (d) 0.33 m s−10.33\,\text{m s}^{-1}
