Problem

A car travels 50 m50\,\text{m} east in 5.0 s5.0\,\text{s} and then 50 m50\,\text{m} west in the next 5.0 s5.0\,\text{s}. Which statement correctly describes its average speed and average velocity for the entire 10 s10\,\text{s} trip? (a) Both the average velocity and the average speed are 0 m/s0\,\text{m/s}. (b) Both the average velocity and the average speed are 10 m/s10\,\text{m/s} east. (c) The average velocity is 0 m/s0\,\text{m/s}, and the average speed is 10 m/s10\,\text{m/s}. (d) The average velocity is 5 m/s5\,\text{m/s} east, and the average speed is 10 m/s10\,\text{m/s}.
