Question 549078: The highest elevation in North America is 20,320 feet above sea level at Mount McKinely. The lowest elevation is 282 feet below sea level in Death Valley. I need to find an absolute value equation that has the highest and lowest elevations in North America as its solution.
Here's what I've already tried doing: 20,320 + b = c and -282 + b = c
Here's where I'm stuck- I think that this is the right way to start solving this equation, but I'm not sure how to solve it from here, or how to convert it into an absolute value equation.

good so far

the two elevations are 20,602 units apart
___ half of that is 10,301; and the midpoint elevation (halfway between) is 10,019

in your setup; b is the midpoint (negative), and c is half the distance

abs(x - 10019) = 10301
