Question

A mountain's peak is 1,224 feet above sea level while the valley is 339 feet below sea level. What is the elevation drop between the top of the mountain and the bottom of the valley?

Answer 1

Imagine that you have a number line that goes from -500 to 1500. The valley is at -339 and the mountain is at 1224 while 0 is sea level. 339 + 1224 is the total number of feet in between the two points, or 1,563 feet.

Answer 2

1224+339=1563

Answer is 1,563 feet. Hope this helps.
