Answer:
38.6Fahrenheit
Explanation:
Given that the plane reaches 6,000 ft
And for every 1000 ft there is a drop of 1.2 Fahrenheit
Therefore there is a total drop of (6*1.2)
Note There are six one thousand in six thousand
6*1.2=7.2Fahrenheit
Also the temperature on the ground is
45.8 Fahrenheit
The temperature when the plane reaches 6,000 ft will be
45.8-7.2=38.6Fahrenheit
