Answer:
First, I think the right formula is:

A) We first derive the formula given above:

V'(t) represent the drain rate of the tank volume.
B) the units is: gallons/time
C) at V'(10) = 100000/60 = 1666.66 gallons/time.
because the formula V'(t) is constant so it doesn't depend of time.
I'm guessing the answer is B? I tried to isolate r and I got that result. Sorry if it's wrong!
