6. The highest elevation in North America is Mt. McKinley, which is 20,320 feet above sea level. The lowest elevation is Death Valley, which is 282 feet below sea level. What is the vertical distance from the top of Mt. McKinley to the bottom of Death Valley?

7. We will use a number line to represent the situation of the previous problem. 0

8. However we are going to use a vertical number line to represent the situation. 0 0

9. 0 sea level 20,320 -282 Not Drawn to Scale!

10. However we are going to use a vertical number line to represent the situation. 0 sea level 20,320 -282 20,320 feet 282 feet Since 20,320 + 282 = 20,402. The vertical distance between Mt. McKinley and Death Valley is 20,402 feet.
