I don’t understand 3c. I’m sure you guys are right, but I felt the question was not consistent with 3b. Since 60,000 cubic cm oil has already leaked, shouldn’t the time be starting at 30 (constant rate of 2000 cubic cm per minute) minutes? Why should we say that at t = 0, there is 60,000 cubic cm of oil already leaked? t = 0 should represent the time in which oil started to leak; not the time in which the recovery device started. Whatever. I’ll accept the point deduction and I understand the official reasoning, but due to stress/anxiety that is how I approached the question during test day.
