Answer:


Step-by-step explanation:

Average change in elevation means,

elevation in 1 minute.

Given,

the diver descended 42.56 feet in 11.2 minutes.

So, we have to find how many feet he dives in 1 minute.

Now,

In 1 minute he dives,

[tex]\frac{42.56}{11.2}[/tex]   feet

=3.8

So, the average change in elevation is   3.8 feet per minute
