A man is swimming at 10 feet below sea level. Then he descends 1 feet and then ascends 5 feet. What is the man's new location?
10 feet below sea level is written as -10
He descends 1 foot. Since descending is negative depth, we have:
-10 - 1 = -11
Then he ascends 5 feet, so we add:
-11 + 5 = -6 or 6 feet below sea level
10 feet below sea level is written as -10
He descends 1 foot. Since descending is negative depth, we have:
-10 - 1 = -11
Then he ascends 5 feet, so we add:
-11 + 5 = -6 or 6 feet below sea level
