Please Help A submarine descends at a rate of 2.6 kilometers per hour
If the ocean floor is 6.24 kilometers below sea level, how long will it take for the submarine to descend to the ocean floor?Round to the nearest tenth

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

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
