Question

The ground temperature at an airport is 10 C. The temperature decreases by 5.6 C for every increase of 1 kilometer above the ground. What is the temperature outside a plane flying at an altitude of 5 kilometers?

Answer 1

ground temp is 10

decreases 5.6 per kilometer above ground

The temperature at an altitude of 5 kilometers would be 10 - (5.6)(5) = 10 - 28 = -18

So the answer is -18 C
