Question

The highest point measured above sea level is the summit of Mt. Everest which is 8,848m above sea level and the lowest point is Challenger Deep at the bottom of Mariana Trench which is 10911m below sea level. What is the vertical distance between these two points?

Answer 1

The lowest point =$10,911m$

The highest point =$8,848m$

Let, distance above sea level be positive, so distance below sea level will be negative, as they are on opposite side of sea level.

Therefore, the vertical distance between two points

$\begin{array}{c}=(8848-(-10911\left)\right)m\\ =[8848+10911]m\\ =19759m\end{array}$
