Work Step by Step

Finding the difference in elevation means that the higher elevation must be subtracted by the lower elevation. The higher elevation is $20320$ feet above sea level, and the lower elevation is $282$ feet below sea level. This second value can be expressed as $-282$ in the calculation, since the numbers are relative to sea level. Thus: $20320 - (-282) = 20602$ feet
