Calculate the approximate air temperature outside the plane flying at an altitude of 10500m

Calculate the approximate air temperature outside the plane flying at an altitude of 10500m, if the air temperature near the earth’s surface is + 20C.

When calculating this task, you must initially take into account that, for every 1000 meters, the temperature drops by 6 degrees. Accordingly, initially we need to find out how many units the temperature should drop, and then calculate it based on 6 degrees. 10500/1000 = 10.5 km, 10.5 km x 6C = 63C, + 20C – 63C = – 43C. The approximate temperature overboard is -43C.
