Calculus (yet again)! The water level of a certain body of water is changing at a rate of W(t) = \frac{1}{2}cos(3 - \frac{t}{2}) inches per hour, where t represents hours since 12 a. m.
What is the average hourly number of inches that the water level changes for this lake in one day?

I'm pretty sure that the number of inches that the water changes in one day would be represented by \int\limits^2_0 {W(t)} \, dt (where the number on top of the integral is a 24), but how would I set up an integral for the average hourly number of inches? Thank you so much!
