Question

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?

A) 0.02°F/ft
B) 0.04°F/ft
C) 0.06°F/ft
D) 0.08°F/ft

Answer 1

The rate of temperature change is 0.02°F per foot as the airplane climbs, corresponding to Option A.

Step-by-step explanation:

The question asks for the rate of temperature change in degrees Fahrenheit per foot when an airplane ascends in the sky.

Given that the temperature drops 20 degrees Fahrenheit for every 1,000 feet the airplane climbs, we can calculate the rate of change by dividing the change in temperature by the change in altitude.

The calculation is as follows:

• Change in temperature = 20°F
• Change in altitude = 1,000 ft

Rate of temperature change = 20°F / 1,000 ft = 0.02°F/ft

Therefore, the rate of temperature change is 0.02°F per foot, which corresponds to Option A.
