Question

temperature suppose there is a 1.2°f drop in temperature for every thousand feet that an airplane climbs into the sky. if the temperature on the ground is 57.8°f, what will be the temperature when the plane reaches an altitude of 7,000 ft? the temperature will be °f. (type an integer or a decimal.)

Explanation:

Step1: Calculate number of thousand - foot intervals

The plane climbs to 7000 ft. The number of thousand - foot intervals is $\frac{7000}{1000}=7$.

Step2: Calculate total temperature drop

Since there is a $1.2^{\circ}F$ drop per thousand - foot interval, the total temperature drop is $1.2\times7 = 8.4^{\circ}F$.

Step3: Calculate temperature at altitude

The ground - temperature is $57.8^{\circ}F$. So the temperature at 7000 ft is $57.8-8.4 = 49.4^{\circ}F$.

Answer:

$49.4$
