Two california landmarks, mt whitney and death valley, are the highest and lowest points in lower 48 states. the difference in elevation is 4,504 meters. the elevation of death valley is -86 meters. what is the elevation of mt. whitney?

We can find out he answer to the question by using the information given.
Since we know that Death Valley is the lower of the two spots, we can assume that we can add the difference in elevation to Death Valley to get the elevation of Mt Whitney.
-86+4,504=4,418
Th elevation of Mt Whitney is 4,418 meters above ground.
Hope this helps!
