Question

As an aircraft rises, the temperature falls. You can determine the change in temperature between the ground andthe altitude the aircraft has reached by using the formula c = -6.7 (a/2000) What is the change of temperature (c),in degrees Fahrenheit, at an altitude (a) of 1500 ft?

Answer 1

The formula given is:

$c=-6.7(\frac{a}{2000})$

Where

c is temp

a is altitude

We want to know temperature (c) at altitude of 1500 (a)

We plug in 1500 into a and figure out c, simple!

Lets do this:

$\begin{gathered} c=-6.7(\frac{a}{2000}) \\ c=-6.7(\frac{1500}{2000}) \\ c=-6.7(0.75) \\ c=-5.025 \end{gathered}$

The temperature at an altitude of 1500 feet is:

$c=-5.025$
