Answer:
80 feet below sea level
Explanation:
We know that the rate of the diver is 2 ft / min. The time we are given is 40 minutes, so to find out how many feet the diver has descended, we multiply the rate by the time:
(2 ft / min) * (40 min) = 80 ft
Thus, the diver is 80 feet below sea level after 40 minutes.
Hope this helps!
