Question

Suppose there is a 1.8°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 56.5°F, what will be the temperature when the plane reaches an altitude of 8,000 ft?

A. 42.1°F
B. 49.7°F
C. 50.1°F
D. 57.7°F

Answer 1

The temperature when the plane reaches an altitude of 8,000 ft will be 42.1°F.

Step-by-step explanation:

The temperature decreases by 1.8°F for every thousand feet the airplane climbs. Therefore, we can calculate the decrease in temperature when the plane reaches an altitude of 8,000 ft by multiplying the drop in temperature per thousand feet by the number of thousands of feet the plane has climbed.

Drop in temperature = 1.8°F/1000 ft x 8,000 ft = 14.4°F

To find the final temperature, we subtract the drop in temperature from the initial temperature on the ground.

Final temperature = 56.5°F - 14.4°F = 42.1°F

Therefore, the temperature when the plane reaches an altitude of 8,000 ft will be

42.1°F
