Answer:
I think 2.15
because 309.60 divided to 2.15 is equal to 144
The slope of the function is most positive either side of x=0 and x=2π.
On the interval [0, π/4], the average slope is

On the interval [7π/4, 9π/4], the average slope is

The average rate of change is highest on the intervals [0, π/4] and [7π/4, 9π/4].
The answer to this question is x=5
