Blank Space needs to be filled with the number of feet per hour that the Nautile must dive to reach the maximum depth. This can be found by dividing the maximum depth (20,000 feet) by the time it takes to reach that depth (20 hours).
So Blank Space should be filled with:
20,000 feet / 20 hours = 1,000 feet per hour
Therefore, the Nautile must dive at a speed of 1,000 feet per hour to reach the maximum depth.
