Question

An airplane is flying at an altitude of 3,000 ft. The pilot dives 630 feet and then rapidly climbs 1,048 feet. The pilot then dives again 888 feet before making another climb of 1,067 feet. How far above the ground is the airplane?

Answer 1

The answer is 3597. You subtract when it says he's diving because he's losing altitude and you add when it says hes climbing because hes going up.
