Answer:
[tex]Sea\ Level = 0\ ft[/tex]
The farthest point is the Challenger Deep
Step-by-step explanation:
Given
[tex]Highest = +29029ft[/tex]
[tex]Least = -35,797ft[/tex]
Solving (a): The sea level
Both elevations had signs in front of them.
The sea level is the point at the neutral level, neither positive nor negative.
Hence:
[tex]Sea\ Level = 0\ ft[/tex]
Solving (b): Farthest Point.
The farthest point is the one with the highest magnitude.
Comparing
[tex]Highest = +29029ft[/tex] to [tex]Least = -35,797ft[/tex]
-35,797 ft has the highest magnitude.
Hence:
The farthest point is the Challenger Deep
