#### Answer:

speed = 3.4

velocity = 0.2

#### Explanation:

The average speed is the total distance traveled divided by the total time.

In this case, the object travels

speed = distance/time =

The average velocity is the final displacement from the start point, divided by the total time. Since the object traveled

velocity = displacement/time =

(also, it really helps to draw a diagram)
