Question

Suppose there is 1.4 a drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 64.2​, what will be the temperature when the plane reaches an altitude of ​8000?

Answer 1

The temperature will be 53

Explanation:

Here, we are told that there is a temperature drop for every 1000 feet rise into the sky

Now, for 8000 ft, there will be 8 drops

Each drop is 1.4;

So 8 drops will be 1.4 * 8 = 11.2

So to get the current temperature, we simply go on to subtract from what we had initially

Mathematically, that will be

64.2 - 11.2 = 53
