Question

Temperature and Altitude. On a certain day, the temperature on the ground is 66 degrees Fahrenheit, and the temperature at an altitude of A feet above the ground is found from the expression 66 − A/300. Find the temperature at the 18,000 feet.? °F

Answer 1

Given:

The temperature at an altitude of A feet above the ground is found from an expression,

$T=66-\frac{A}{300}$

The temperature at 18000 feet is,

$\begin{gathered} T=66-\frac{18000}{300} \\ T=66-60 \\ T=6^{\circ}F \end{gathered}$

Answer: The temperature at 18000 feet is 6 degrees Fahrenheit.
