Answer:

The submarine descends with an average speed of 1000 feets/hour during 2 hours

Step-by-step explanation:

You can solve this problem using a rule of 3:

In 2 hours, the submarine descends 2000 feets
In 1 hour, the submarine descends 2000/2 * 1 = 1000 feets.

Note that we dont know for sure that the submarine is descending at constant speed, but we can confirm that the average speed of the submarine is 1000 feets per hour.

I hope I could help you!
