I am stilling struggling to understand the question since I'm not english native speaker. Could anyone help explain the meaning of "deep end" and "shallow end" mentioned in the question? Without understanding correctly, I cannot depict the question....
A swimming pool is typically constructed in a rectangular fashion (L X B). It doesn't really matter what the deep and shallow ends actually are, other than the fact that they are opposite ends of a swimming pool.
Shallow end (4ft depth) Deep end (17ft)

The question indicates the race length as 2-length, which means the swimmer:
- goes from one end to and another
- and returns to that end to finish the race
Hope this helps.
