Question

A scuba diver dove from the surface of the ocean to an elevation of −89 9/10

Answer 1

He ascended 71ft and it took him 6.88 minutes to do so

Answer 2

Answer:

he rose by 71 feet and it took him 6.88 mins to do so.

Step-by-step explanation:

So we know that the diver is going up in elevation cause he is ascending and he ascended 71 ft. Along with the fact that the total dive was 20 1/8 mins with roughly converts to 20.13 mins and if we take that number and subtract the amount of time he stayed at the elevation of 71ft we know that it took him 6.88 min to rise to the elevation of -18.9.
