[Math] Finding the average temperature over a certain amount of time

Question

I'm assuming you use some time of equation such as the Mean Value Theorem of Integrals to find the average here, but the equation is not represented in the form of an integral, so I'm not entirely sure how to begin.

Answer 1

Basically, by just using definition of average

$T_{avg}=\frac{1}{30}\int_0^{30} { T(t) dt }$
