Determine the approximate height of the mountain if it is known that its movable air temperature is plus 16 degrees Celsius at the top of minus 8 degrees Celsius

With an increase in altitude for every 1000 meters, the temperature decreases by an average of 6 degrees.
In our case, the temperature difference between the foot and the top of the mountain is 24 degrees Celsius (16 – (- 8) = 24);
The height of the mountain is obtained by dividing the temperature difference between the foot and the top of the mountain by its average decrease for every 1000 meters: 24: 6 = 4
Answer: the height of the mountain is 4 kilometers.
