Question

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 the submarine to descend to the ocean floor?

Answer 1

Answer:

2.4 hrs

Step-by-step explanation:

Dividing 6.24 by 2.6 will give you 2.4 hrs

Answer 2

Answer:

Find out the how long will it take the submarine to descend to the ocean floor

To proof

Formula

r = \frac{d}{t}r=

t

d

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

2.6 = \frac{6.24}{t}2.6=

t

6.24

t = \frac{6.24}{2.6}t=

2.6

6.24

t = 2.4 hour

it take 2.4 hours the submarine to descend to the ocean floor .

Hence proved

Hope it helps :)
