Answer:
20,602
Step-by-step explanation:
above the sea level. as 20,320
Death Valley,below sea level is -282 feet .
We need to find the difference ( in height ) between the top of Mt. McKinley and the bottom of death valley.
20,320 - (-282) = 20,320 + 282 = 20,602 feet.
So the distance ( height ) from the top of Mt. McKinley to the bottom of death valley is 20,602
