The Assignment question is :

Give an example of a situation in which composite differentiation might be used. Give examples of functions that might be applicable in your situation, and show how the relevant rates of change might be calculated.

My example situation is :

Suppose that a square glacier with a volume of 4 km3 is floating in the Antarctic Ocean. Due to global warming, the volume of the glacier is melting at a rate of 0.3 km3 per year. How fast is it melting if a glacier melts until its length is only 1 km?

Can you solve it by using composite differentiation? You can change the numbers or the problem a bit if you need to.

I made a problem, but I don't know how to solve it....

pls help me, thank you.

let me know if there's any questions.
