It is known that for every kilometer of rise, the air temperature in the troposphere drops by 6 ° C.

It is known that for every kilometer of rise, the air temperature in the troposphere drops by 6 ° C. Determine the air temperature over Moscow, London and Delhi at an altitude of 3 km. If at the surface of the earth it is + 18 ° С, + 14 ° С, + 24 ° С.

When solving such problems, it is worth remembering that if the altitude changes by one kilometer, then the temperature also changes by 6 degrees. However, with an increase in altitude, the temperature decreases, and with a decrease, it rises. Therefore, the following problem can be solved using the following calculations:
18- (6 * 3) = 0;
14- (6 * 3) = -4;
24- (6 * 3) = 6
