The average rate of change of the position of an object with respect to time is the average speed of the object, so to find the average speed of the rock over the interval [5,10], we are going to use the average rate of change formula: 
where
is the average rate of change (the speed)
is the position function evaluated at 
is the position function evaluated at 
is the first point in the interval
is the second point in the interval
We know for our problem that the first point in the interval is 5 and the second point is 10, so
and 
. Lets replace those values in our formula:
We can conclude that the speed of the rock between 5 and 10 seconds is 12 meters per second.
