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
An objects motion or speed is distance divided by time.
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.
Because it doesn't have direction - Velocity is usually used to describe motion in physics because it has both speed and direction.
The average speed of motion is when speed is changing. Speed equals total distance divided by total travel time. Velocity is the speed and direction of an object's motion.
total distance divided by total time
Speed and direction of motion.
When it changes position or something to do with the speed.
