Question

-2 degree drop in temp every 1,000 ft airplane climbs in the sky. Temp on ground is 57 degrees. What is temperature when plane reaches 29,000 ft.

Answer 1

Answer:

(-1) degrees

Step-by-step explanation:

∵ Temperature drop with the increase in every 1000 ft of height = 2 degrees

∴ Temperature drop in every 1 ft = $\frac{2}{1000}$ degrees

∴ Temperature drop in 29000 ft = $\frac{2\times 29000}{1000}$

                                                      = 58 degrees

Temperature on ground = 57 degrees

Temperature at 29000 feet = 57 - 58

                                               = -1 degrees

Therefore, temperature at 29000 feet is -1 degrees.
