Answer 9

Notice that you want to find the average change in temperature each week, which means that you expect to find a quantity which is a temperature change \(\underline{\textrm{per week}}\).

Let's say that the temperature changed by some amount \(\Delta T\) over a time interval \(\Delta t\). Can you see what \(\dfrac{\Delta T}{\Delta t}\) might mean in this context?
