Final answer:
The temperature when the plane reaches an altitude of 10,000 feet would be -15.8 degrees.
Step-by-step explanation:
To find the temperature when the plane reaches an altitude of 10,000 feet, we need to know the rate at which the temperature drops as the plane climbs. The question states that there is a 1.3 degree drop in temperature for every thousand feet of altitude gained. So, for 10,000 feet, we can calculate:
Temperature drop = (1.3 degrees/1000 feet) * 10,000 feet = 13 degrees
Therefore, the temperature when the plane reaches an altitude of 10,000 feet would be:
Temperature = Ground temperature - Temperature drop = -2.8 degrees - 13 degrees = -15.8 degrees
