Rounding Mountains
Mount Everest is roughly thirty thousand feet high. Actually that is the height rounded to the nearest ten thousand feet. Mount Cook measures in at roughly ten thousand feet. Again this is the height rounded to the nearest ten thousand feet.
Given these estimates, find the difference between the greatest possible height and the least possible height of the two mountains.
Explain in mathematical terms why this difference is larger than the difference of twenty thousand between the two estimated figures.
Bonus: Name the tallest mountain on the continent where you live and give the height of that mountain? Be sure to tell me where you found the information.
