Answer 12

A mountain climber ascends a mountain to its peak. The peak is 14,020 ft above sea level. The climber then descends 260 ft to meet a fellow climber. Find the climber’s elevation above sea level after meeting the other climber.

–13,760 ft
11,420 ft
13,760 ft
14,280 ft

Answer 13

Just subtract 260 from 14,020. The mountain climber is heading down from his current elevation, so the elevation is dropping. He's going down 260 feet, so that's how much you subtract.

Answer 14

so it will be –13,760 ft
