Question

a mountain climber on Mount Everest is at 29035 FT above sea level a stone at the bottom of the Dead Sea is at 1349 feet below sea level what is the difference in elevation between the mountain climber and the stone

Answer 1

To answer this question, we can see that:

We can see that the climber is 29035 above sea level and the stone at the bottom of the Dead Sea is at 1349 feet below sea level. Then, the difference in elevation between them is:

`D_{\text{elevation}}=29035ft-(-1349)ft=30384ft`

Therefore, the difference in elevation, between the mountain climber and the stone, is 30,384ft.

(We are dealing here with integer numbers, some of them are positive, and others are negative. Above the sea level, we can write elevations as positive numbers. Below the sea level, we write elevations as a negative number. When we subtract positive and negative in this way, we end up with that kind of operation like the one presented above. We had a negative sign by a negative sign. It equals a positive sign. That is why we ended up with a positive sign. )
