Amountain climber ascends a mountain to its peak. the peak is 14,090 ft above sea level. the climber then descends 490 ft to meet a fellow climber. find the climber’s elevation above sea level after meeting the other climber.
a. 14,580 ft
b. 9,190 ft
c. 13,600 ft
d. –13,600 ft

The final elevation from sea level of the first climber is the difference of the elevation of the peak and the number of feet he descended to meet his fellow climber,
                           e = 14,090 ft - 490 ft
                              e = 13,600 ft

Thus, the answer is letter C. 13,600 ft.
