As an airplane rises, the outside temperature drops 3.6°F on the ground when the plane takes off and -43°F at cruising altitude. How high is the plane then?algebra
Let's call the height of the plane H.
From the information given, we can set up the following equation to represent the change in temperature as the plane rises:
H * 3.6 = H * (-43)
By simplifying the equation, we have:
3.6H = -43H
Adding 43H to both sides of the equation, we get:
43H + 3.6H = 0
Combining like terms, we have:
46.6H = 0
Dividing both sides of the equation by 46.6, we get:
H = 0
Hence, the plane is at a height of 0, which means it is still on the ground.
