a question at work popped up and it's been too long since I went to school :p

The total energy [Wh] required to heat the system to temperature T is given by f(T)=1.28T. The effect [W] applied to the system is given by g(T)=378-3.16T. How long does it take to heat the material to say 80 degrees?

Hope someone can help me out, thanks.
