Ten laps = 10*.25 = 2.5 miles. 2.5 miles in 15 minutes = 2.5/15 miles per minute = 60*2.5/15 or 10 miles per hour.

Orbital velocity is the average velocity (or speed) of a planet as it orbits around the sun. It is usually expressed as km/s or mph.
their average speed is greater than their average velocity.
Wind
Their average speed is the harmonic mean of 30 and 45 while their average velocity is zero.
Average - around 45000
Every time the unicycle returns to its starting point, the average velocity equals zero. The total displacement divided by the time.
