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

Nesterboy [21]

Answer: $49.7^{\circ}F$

Step-by-step explanation:

Given

The temperature on the ground is $56.9^{\circ}F$

temperature drop observed is $1.2^{\circ}F\ \text{per 1000 ft}$

The height of the plane is $6000\ ft$

The total increase in height per $1000\ ft$ is $6$ units

Temperature drop is

$\Rightarrow 1.2\times 6=7.2^{\circ}F$

The temperature at that altitude is

$\Rightarrow 56.9-7.2=49.7^{\circ}F$
