The first part of the question is asking you to solve the separable differential equation. It looks like your solution is fine to me. Except you need to re-arrange it a bit. Solve for ##h(t)##.

The second part of the question is 'hinting' at an initial condition. In particular: ##h(5) = 2##. So what does that tell you about the rest of the information?
