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 generally decreases at a rate of about 5.4°F per 1000 feet. This is known as the lapse rate, and it occurs due to the decrease in air pressure with increasing altitude.
It depends on the on what sphere of the atmosphere you are talking about. At ground level (troposhere) it gets colder as altitude rises. Once the altitude reaches the stratosphere the temperature becomes warmer then cools down again as it reaches the stratopause, and continues to decline as altitude increases in the mesophere until the mesopause. The temperature then rises significantly when the altitude is high enough to be considered the thermosphere.
Air pressure and temperature do not change in the same way with altitude. As altitude increases, air pressure decreases because there is less air mass above pushing down. This leads to a decrease in temperature with altitude at a rate of about 2 degrees Celsius per 1,000 feet due to the decrease in pressure causing the air to expand and cool.
In the exosphere, temperature increases with altitude. This is because the particles in the exosphere are far apart, so there is no transfer of heat through conduction or convection. Instead, the few particles present gain energy from solar radiation, causing an increase in temperature as altitude increases.
Usually, all commercial jet aircraft cruise between 30000 and 40000 feet.
The average temperature decreases by about 3.5F per 1000 feet increase in altitude.
The rate of temperature drop per 1000 feet in altitude is approximately 3.5F.

Answer: 40000 km = 131,233,595.800 '
As altitude increases, the temperature of air generally decreases at a rate of about 5.4°F per 1000 feet. This is known as the lapse rate, and it occurs due to the decrease in air pressure with increasing altitude.
As altitude increases by 1000 feet, the temperature typically decreases by about 3.5F. This change in temperature can impact weather patterns by influencing air pressure, wind patterns, and the formation of clouds and precipitation.
40,000 feet = 12.192km
40000 feet = 7.6 miles
