11. Can speed usually ever be negative? Can velocity be negative?

12. If the Daytona 500 lasts 3 hours what is the avg speed of the race? What is the avg velocity?

14. You travelled to class, you sat for 2 hours and then you travelled home. For the entire trip what is your average velocity? What is your average speed?
