Denali, North America's highest peak, is 20,310 feet above sea level. Death Valley is 282 feet below
Artyom0805 [142]

Answer:

The difference between the two position = 20,028 feet

Step-by-step explanation:

North America highest peak distance above sea level = 20,310 feet

Death valley distance below the sea level  = 282 feet

Let the sea level be = X

Highest peak point = Y

Death valley point = Z

So As per question

Distance from X to Y = 20,310 feet

Distance from X to Z = 282 feet

So, difference between two points = (X + Y )  - (X + Z ) = Y - Z

So , Y - Z = (20,310) - (282) = 20,028 feet

Hence the difference between the two position = 20,028 feet  Answer
