As part of a training exercise, a submarine captain ordered the vessel to descend 250 feet, level off for 5 minutes, then repeat.
If the sub started at the ocean's surface, find its depth after the 8th dive. Use a signed number.
Correct Answer
-2,000 ft
Explanation
Each dive descends 250 ft. After 8 dives:
\[ 8 \times (-250) = -2{,}000 \]
The submarine is 2,000 feet below sea level after the 8th dive.
