    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    -2 ln |20-2h| = kt + c

    kinda lost. solving (i) would be enough for me

    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?
