speed and average velocity of the truck?
O average speed = 2 meters/secong
average velocity = 2 meters/second
O average speed = 2 meters/second
average velocity = 0 meters/second
average speed = 10 meters/second
average velocity = 10 meters/second
average speed = 0 meters/second
average velocity = 10 meters/second
