Question

temperature. suppose there is a 1.9°f drop in temperature for every thousand feet that an airplane climbs into the sky. if the temperature on the ground is 55.2°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 the number of thousand - feet intervals

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

Step2: Calculate the total temperature drop

Since there is a $1.9^{\circ}$F drop for each thousand - feet interval, the total temperature drop is $1.9\times7 = 13.3^{\circ}$F.

Step3: Calculate the temperature at 7000 ft

The ground - temperature is $55.2^{\circ}$F. The temperature at 7000 ft is $55.2-13.3 = 41.9^{\circ}$F.

Answer:

$41.9$
