Vavg is equal to total distance divided by total time, assuming all time was spent riding as stated. Total distance is 10 +10 = 20. Total time duration is 10/20 +10/10, or 3/2 hours. Dividing 3/2 into 10, we get a long division problem of 40/3. The answer to that is 13.3 mph, rounded to one decimal place.

If you poll 100 people on their average speed for that ride, 90% will say 20 MPH and .009% will say 13.3 mph :-)

Rene Descartes walks into a bar, the bartender asks if he wants a drink. Descartes replies, "I think not." And he disappeared.
Just in case the OP was being philosophical and not mathematical.
