The science class built a robot that travels 5 m north in 10 s. what is the robot's average velocity?
a. 0.5 m/s
b. 0.5 m/s north
c. 2 m/s
d. 50 s/m north

Average velocity =

      (distance between start-point and end-point) / (time to travel)
 AND
     (direction from start-point to end-point)

Distance between start and finish . . . . . 5 m
Time to travel . . . . . 10 s
Direction from start to finish . . . north

       Average velocity = 0.5 m/s north
