At 20 meters per minute, the sub would be descending at 60 * 20 = 1200 meters per hour

You're welcome -- but my answer doesn't match any of your answers.
Answered by Reiny
I see 3600 m mentioned in 3 of your choices. Agreeing with Ms. Sue that the answer does not match any of your choices, I suspect a typo and your rate of descent is 30 m/min.
