pogonyaev

Answer: 55.1°F

Step-by-step explanation:

We are informed that there is a 1.6°F drop in temperature for every thousand feet that an airplane climbs into the sky, if the plane reaches an altitude of 2,000ft, the drop in temperature will be:

= 1.6° × 2

= 3.2°F

If the temperature on the ground is 58.3°F, then the temperature when the plane reaches an altitude of 2,000 ft will be:

= 58.3°F - 3.2°F

= 55.1°F
