What is the air temperature at the top of a 1500m mountain, if at its foot it is +20? at what altitude will the air temperature be +14?

1. With an increase of 1 km, the air temperature decreases by 6 degrees (1 km – -6 degrees, 2 km – -12 degrees). Then, at an altitude of 1.5 km (1500 m), the temperature will drop by: 6 + 6/2 = 6 + 3 = 9 (degrees). The temperature at the top of the mountain will be: 20 – 9 = 11 (degrees).
2. The air temperature is 14 degrees, which is 6 degrees lower than the temperature at the foot of the mountain, which means at an altitude of 1 km.
Answer: 11 degrees; 1 km.
