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-(A)/(300)`

The temperature at 18000 feet is,

`\begin{gathered} T=66-(18000)/(300) \\ T=66-60 \\ T=6^(\circ)F \end{gathered}`

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