Question

Mt. Everest has an elevation of 8848 m above sea level. Mariana Trench's deepest point is 19842 lower than the height of Mt. Everest.
How many metres below sea level is the deepest point of Mariana Trench?

Answer 1

Given,

Elevation of Mount Everest above sea level is 8848 metres.

Mariana Trench's deepest point is 19842 lower than the height of Mount Everest.

To find,

The depth of the Mariana Trench below the sea level.

Solution,

Mariana Trench's deepest point is certain metres lower than the height of the Mount Everest means,the result of addition of the height of the Mount Everest and the depth of the Mariana Trench

Let,the depth of the Mariana Trench below sea level = x metres

So,from the given data,we get that

x+8848 = 19842

x= 19842-8848

x = 10994

Hence,the depth of the deepest point of the Mariana Trench below the sea level is 10994 metres.
