Definition
Zero since the displacement is zero. 


Term
What is the average speed of a runner who finishes a lap around a 1/4 mile track in 3 minutes? 

Definition
Average speed is distance divided by time. 1/4 mile divided by 3 minutes = 1/12 of a mile per minute or 5 mph. 


Term
If you drive 30 miles at 60 miles per hour and then slow down to 20 miles per hour for the next 10 miles, what was your average speed? 

Definition
Average speed is distance divided by time. You have driven 40 miles in 1 hour, so your average speed is 40 mph.
