If the ocean floor is 6.24 kilometers below sea level,
To Find : how long will it take the submarine to descend to the ocean floor?
Solution:
submarine descends at a rate of 2.6 kilometers per hour.

ocean floor is 6.24 kilometers below sea level,
Hence Distance to be covered = 6.24 km
Time Take = Distance / Speed
= 6.24 / 2.6
= 2.4 hr
submarine will take 2.4 hr to descend to the ocean floor
