Answer :
Final answer:
The temperature when the plane reaches an altitude of 3,000 ft will be 44.3°F.
Explanation:
The subject of this question is Mathematics. The question asks us to determine the temperature when an airplane reaches an altitude of 3,000 ft, given that there is a 1.4°F drop in temperature for every thousand feet the airplane climbs.
To find the temperature at 3,000 ft, we can use a proportion. Since the plane climbs 3,000 ft, there will be 3,000/1,000 = 3 segments of 1,000 ft. Multiply the drop in temperature (1.4°F) by 3 to find the total drop in temperature. Subtract this from the initial temperature to get the final temperature.
Initial temperature - (Drop in temperature per segment * Number of segments) = Final temperature
48.5°F - (1.4°F * 3) = 48.5°F - 4.2°F = 44.3°F
Therefore, the temperature when the plane reaches an altitude of 3,000 ft will be 44.3°F.
