Average Speed
You also can input the distance of the course or a particular segment of the course of
the race you are watching. That distance is used along with the elapsed time,
cumulative elapsed time, or lap time measured by the watch to calculate and display
the average speed for the course or segment.
The average speed that appears for an elapsed time, cumulative elapsed time, or lap
time is calculated based on the times described below.
Elapsed time: Time from the point the stopwatch operation is started up until it was
stopped.
