    Review Questions:
    9. The car maintains constant speed but different velocity since it changes direction.

    10. Acceleration is the rate at which velocity changes, and velocity is the speed and direction.

    11. 10 km/h x s

    12. 0

    One Step Calculations:
    9. 5km

    10. 10 km/h x s

    11. 4 km/h x s

    12. 5 m/s^2

  4. 5.a=d/t, a=15k/30min
    6. 25km/h=d/30min
    7.speed is the description of how fast and velocity is how fast and in what direction
    8.no it doesnt
