Question 10 (a) 

An animal foraging in a food patch has a net energy gain of by the time it has been foraging for min (where is nonnegative and ). (a) Let be the average net energy gained per unit time. Write down an expression for in terms of and .

Make sure you understand the problem fully: What is the question asking you to do? Are there specific conditions or constraints that you should take note of? How will you know if your answer is correct from your work only? Can you rephrase the question in your own words in a way that makes sense to you? 
If you are stuck, check the hint below. Consider it for a while. Does it give you a new idea on how to approach the problem? If so, try it! 
Hint 

Consider the average over the interval . Find the change of a function value and the change of a time in the interval first. 
Checking a solution serves two purposes: helping you if, after having used the hint, you still are stuck on the problem; or if you have solved the problem and would like to check your work.
