Question

If a submarine dives 378 feet in 14 seconds, the average change in elevation is

Answer 1

Answer: The average change in elevation is 27 feet per second.

Step-by-step explanation:

 A submarine dives = 378 feet

          Time taken in the total diving = 14 seconds.

So, according to the question, the average change in the elevation  can be calculated by

                            ⇒ Feet per second = feet/ second

                             ⇒ the average change = 378/14

                            ⇒ elevation = 27 feet per second.

Change in elevation is basically the distance covered in one second.
