On a standard day, the temperature at 40,000 feet is approximately -69.7F.
When you're above the surface you are dealing with layers of the atmosphere, not layers of the Earth. At 40,000 feet you will be either in the upper troposphere or the lower stratosphere depending or you latitude.
As altitude increases, the temperature of air gets considerably colder and once you get past about 15,000 feet it gets colder faster and faster.
as altitude increases temperature decreases
Temperature decreases as altitude increases.
Temperature changes with an increase or decrease of altitude. This change is known as the "lapse rate" and it varies depending on the amount of moisture in the particular mass of air. The "dry adiabatic lapse rate" (for dry air masses) is a temperature decrease of about 3 degrees C per thousand feet of altitude, while the "wet adiabatic lapse rate" (for moist air masses) is a temperature decrease of about 1.66 degrees C per thousand feet of altitude. For average conditions, a figure of 3.5 degrees F (2 degrees C) per 1000 feet is commonly used.
Usually, all commercial jet aircraft cruise between 30000 and 40000 feet.

Answer: 40000 km = 131,233,595.800 '
As you gain altitude in the troposphere, the layer of atmosphere closest to the ground and extending about 8 miles up, the temperature will decrease by 1 degree Fahrenheit for every 200 feet.
as altitude increases temperature decreases
Normally, temperature decreases as altitude increases. In a temperature inversion, the temperature increases as altitude increases, up to the level of air that is causing the inversion. See "Temperature change as altitude increases?" for info on how temperature normally decreases with altitude when there is not a temperature inversion.The rate at which the temperature goes down is down 1.1 degrees celsius for every 500 feet you go up.
At about 30,000 feet, the air is thinner and the aircraft has little resistance at that height, because of that little resistance the plane can fly much further
