Given : A submarine descends at a rate of 2.6 kilometers per hour.

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:

The submarine descends at a rate of 2.6 kilometers per hour.

Speed = 2.6 km/hr

The ocean floor is 6.24 kilometers below sea level,

Distance to be covered = 6.24 km

Time= Distance / Speed

= 6.24 / 2.6

= 2.4 hr

The submarine  will take 2.4 hrs  to  descend to the ocean floor
