An airplane cuts through the morning sky. For every 1,000 feet that it climbs, the outside temperature drops 20 degrees Fahrenheit. What is the rate of temperature change in degrees Fahrenheit per foot? Complete the steps below to answer the question.

PART A
Write the change in elevation and the change in temperature as rational numbers.
Part B
Write a numerical expression to represent the rate of temperature change in degrees Fahrenheit per foot.
Part C
What is the rate of temperature change in degrees Fahrenheit per foot?

Part D
Now, consider the reverse situation: as the airplane descends, or drops, 1,000 feet in the air, the temperature rises 20 degrees Fahrenheit. Write a numerical expression representing the rate of temperature change in degrees Fahrenheit per foot.

Part E
What is the rate of temperature change in degrees Fahrenheit per foot?

Part F
How is the rate you found in part E related to the rate you found in part C? What does this mean?
