Answer 2

The difference in height between the top of Mt. McKinley and the bottom of death valley is 20,602 feet.

Explanation:

Consider the provided information.

Let say the sea level is at the zero, if a point is below sea level then we will indicate it by placing a negative sign in the front of the number and if it is above the sea level then we will indicate it by placing a positive sign or no sign in the front of the number.

Now consider the provided information.

Mt. McKinley, which is the highest elevation in North America, is 20,320 feet above sea level. Death Valley,

Thus, the number can be written as 20,320 as it is above the sea level.

Death Valley, which is the lowest elevation in North America, is 282 feet below sea level.

Thus, the number can be written as -282 as it is below the sea level.

Now we need to find the difference in height between the top of Mt. McKinley and the bottom of death valley.

20,320-(-282)

20,320+282

20,602

Hence, the difference in height between the top of Mt. McKinley and the bottom of death valley is 20,602 feet.
