In a 200-m footrace, one participant covers the first 100 m with an average velocity of 10 m/s and the second 100 m with the average velocity of 8 m/s. What is your average velocity for the entire 200 m?
------------
Avg of a round-trip, or for 2 equal distances:
= 2*10*8/(10+8)
= 80/9
= 8.888... m/sec
