Question

The ground temperature at airport is 12 degrees. The temperature decreases by 5.2 degrees for every mile above ground. What would be temperature outside plane located at 3 miles above the airport

Answer 1

The outside plane located at 3 miles above the airport is of -3.6 degrees.

Explanation:

The ground temperature at airport is 12 degrees. The temperature decreases by 5.2 degrees for every mile above ground.

This means that the temperature in n miles above ground is given by:

`T(n) = 12 - 5.2n`

What would be temperature outside plane located at 3 miles above the airport

This is T(3). So

`T(3) = 12 - 5.2*3 = 12 - 15.6 = -3.6`

The outside plane located at 3 miles above the airport is of -3.6 degrees.
