            SPEED   TIME      DISTANCE
Part1        5       x           5x
Part2        10      y           10y
Total              x+y           35
AVERAGE      7

Average speed is total distance divided by total time.

Note that total time can be found just from the average speed, the first equation.

------ 5 hours total time.
