Final answer:
The temperature at an altitude of 6,000 ft is 36.4°F
Step-by-step explanation:
To find the temperature when the plane reaches an altitude of 6,000 ft, we need to calculate the temperature drop.
Given that there is a 1.8°F drop in temperature for every thousand feet, we can calculate the temperature drop as follows:
Temperature drop = (1.8°F/1000 ft) x (6000 ft)
Temperature drop = 10.8°F
To find the temperature at 6,000 ft, we subtract the temperature drop from the initial temperature on the ground:
New temperature = 47.2°F - 10.8°F
New temperature = 36.4°F
