Divide the total distance traveled by the total time elapsed.
Hint: If you're looking for miles per hour (miles/hour), divide miles by hours.

Average speed over a period of time = (distance covered in a period of time) divided by (time it took to cover the distance).
It is the product (multiplication) of the average speed and the time interval.
Average speed is an average value of speed over a given time. If your speed is constant (not changing), then your average speed will equal your speed at any given moment in time.
No. if you are accelerating from rest, for example, and reach 80 mph starting from 0, your average velocity is 40 mph, but your speed is 80 mph at the end. Generally we speak of average speed, so if it takes one hour to go 60 miles your average speed is 60 mph, even though you may have slowed and then gone faster at certain times.
The average speed over the 6 hour period is 56.2 miles per hour.
