total distance divided by total time
The same way you calculate the average speed of any object. You divide distance by time.
Cycler's speed = 400/20 = 20 meters per second. Skier's speed = 1500/60 = 25 meters per second. The skier's average speed during his minute is 25% faster than the cyclist's average speed during his 20 seconds.
Total distance divided by total time
If it "does not travel", the speed is zero. Not much to calculate there.
The actual speed can change all the time. You can calculate the average speed by dividing the total distance traveled by the total time.
Find the distance of the race. Find the cyclist's start time. Find the cyclist's finish time. Elapsed time = Finish time - Start time. Average speed = Distance/Elapsed time.
1/18
W/4 mph
16 km is not a speed (average or otherwise), it is a distance. It is therefore impossible to answer this question.
You measure the entire and divide that by the total.
the speed

I'm sure that average speed would be easier to calculate than instantaneous speed. To calculate average speed, just take the time that it takes to travel between two points, and divide that into the distance between the points.

40km per hour
