1. The problem statement, all variables and given/known data Liquid is pouring into a container at a constant rate of 30cm^3s^-1 At time t seconds liquid is leaking from the container at a rate of 2/15 V cm^3s^-1, where V cm^3 is the volume of liquid in the container at that time. Show that -15 dV/dt = 2V - 450 2. Relevant equations: None 3. The attempt at a solution At T second it leaking so the initial volume will be 30t. I don't know where to go from there.
