Question

Suppose a rescue helicopter is 700 feet above sea level descends 300 feet to search for debris or any other signs of a submarine in trouble. When the captain does not see anything, he ascends 200 feet and stays at that altitude while he tries to get a radio signal from the submarine. A few moments later he speaks to the captain and is informed that the submarine is 122 feet below sea level. How far is the helicopter from the submarine?

Answer 1

Answer:

The helicopter is 722 feet from the submarine.

Step-by-step explanation:

700 - 300 = 400

400 + 200 = 600

600 - 122 = 722

Answer 2

700-300+200=600
600+122=722

ANS 722
