Ask Richard swim underwater his elevation changes and family for six minutes altogether a change in -30 feet what was the change in elevation drink each minute what was the change in elevation during each minute

The change of elevation during each minute is -5 feet per minute

Step-by-step explanation:

Here in this question, we are interested in calculating the change in elevation during each minute given that there was a total change of -30 feet in six minutes altogether.

Now, to calculate the change in elevation during each minute, we need to assume that the change in elevation per each of the minutes is the same.

So to calculate the change in elevation during each of the six minutes, we simply divide the total change in elevation by the total number of minutes.

Mathematically, that would be -30 feet/6 minutes = -5 feet per minute

the answer is b
