Answer
Find out the how long will it take the submarine to descend to the ocean floor
To proof
Formula

where d = distance traveled (or descended),
r = rate of travel , t = time
As given
A submarine descends at a rate of 2.6 kilometers per hour. If the ocean floor is 6.24 kilometers below sea level .
put all the values in the above formula


t = 2.4 hour
it take 2.4 hours the submarine to descend to the ocean floor .
Hence proved
The answer for the question is 4
