Question

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 56.9°F, what will be the temperature when the plane reaches an altitude of 6,000 ft?​

Answer 1

Answer:
`49.7^(\circ)F`

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* 6=7.2^(\circ)F`

The temperature at that altitude is

`\Rightarrow 56.9-7.2=49.7^(\circ)F`
