Answer:
degrees Celsius.
Step-by-step explanation:
Let x represent number of kilometers.
We have been given that the temperature decreases by 6.8 degrees Celsius for every increase of 1 kilometer above the ground. So temperature decreased in x hours would be .
The ground temperature at Brigham Airport is 12 degrees Celsius. The temperature at an altitude of x kilometers would be .
To find temperature outside a plane flying at an altitude of 5 kilometers, we will substitute in our expression as:
Therefore, the temperature outside a plane flying at an altitude of 5 kilometers would be degrees Celsius.
I hope this helps, this is close I hope!
