<em>The question is incomplete as the function is not given. However, the following explanation will guide you.</em>

The average rate of change is calculated using;
Where
Take for instance;
The function is:
We have to solve for f(-1) and f(5);
i.e.
Substitute -1 for a and 5 for b
Substitute values for f(5) and f(-1)

s = hours it takes the small pipe on its own.
L = hours it takes the large pipe on its own.
we know the small pipe can do it in 11 hours total, so s = 11, so, how much of the whole job has the small done in 1 hour only?
well, if it takes 11 hours to do the whole thing, in 1 hour it has done only 1/11 of the whole job.
we know both pipes working together can do it in 6 hours flat. So in 1 hour only, both of them have done only 1/6 of the whole thing.
in that 1 hour, how much has the large one done? well, it has only done 1/L of the job.
and you can round that up as needed.
