The correct answer is probably not the one you come up with first. Requires you to have a good grasp of the scenario and some lateral thinking.

He travels 9 miles a day, so just over 2.

Interesting. I too think its 16. travels net 1 a day, after 15 days he's 15 miles. On the 16th day he'll row miles 15 to 20 and obviously stop so he's not gonna drift back down.
In fairness I think Hell's answer would get some points for thinking outside the box!!
