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

If we consider straight vertical distance, 
then the distance between them should be 8848 + 10911 = 19759 m.

Answer 2

Answer:

19759 m

Step-by-step explanation:

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

summit of Mt. Everest  is 8,848m above sea level

bottom of Mariana Trench  is 10911m below sea level

Both are in opposite direction to sea level

Hence Vertical distance between   summit of Mt. Everest  & bottom of Mariana Trench would be sum of both distances

8848 + 10911

=  19759 m

to know the exact distance we should know the horizontal distances as well.
