Question

If a submarine dives 378 feet in 14 seconds, the average change in elevation is____feet per second.

Answer 1

Answer:

change in elevation= total dive/ time taken

therefore, 378/14=>27 is average change in elevation

Answer 2

The average change in elevation is 27 feet per second.

Step-by-step explanation:

Given:

           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 = $\frac{feet}{second}$

                              ⇒ the average change = $\frac{378}{14}$

                             ⇒ elevation = 27 feet per second.

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