This question is from the following Princeton Review book: https://books.google.ca/books?id=bkXBRM ... 22&f=false
The question appears on page 430 (question #7), and the correct answer (A) is given on page 441
This should make sense to us, since the two legs of the trip create a right triangle.
The missing side is the hypotenuse, so we can write:
500² + 1200² = (missing side)²
Solve this equation to get: missing side = 1300
In other words, 1300 is the minimum number of miles the captain must sail to return to his original position
