If it takes 68 meters per minute for the ship's ascent, the question is asking us to find how many minutes it will take reach 631 meters.

First, the ship is at a depth of 1583 meters, so to reach 631 meters, it has to go: \(1583-631=952\) meters.

We also have our proportion: 68 meters every 1 minute, so 952 meters in \(\frac{952}{68}=\boxed{14}\) minutes.
