The math problem in K.M. Kaung's novella Black Rice - by Math Poet JoAnne Growney - posted with permission -

Kyi

I have just posted a review of BLACK RICE on amazon.com.
During the next few days  I will make a posting about the novella in my blog
--  and talk a bit about the bathtub math problem you include.  And in the
blog I will link to the amazon.com review.
The problem you pose (on page 26) falls into a category of calculus
problems  -- problems about "related rates."  The information given in your
book is enough to identify a type of problem but more detail needs to be
given to actually solve it. Something about the size of the tub and the
amount of water in it at the start.    It appears, though, that unless the
tub is very very very large, that after eight hours the tub will be full and
water will be overflowing out of it.
(Probably when I post I also will mention that writers seem often to tell of
a character's difficulty with math -- apparently this is a way of making
many readers offer empathy with the character.)
Hope you are well and enjoying writing and painting and other good activity.
Best,
JoAnne
