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 = degrees
∴ Temperature drop in 29000 ft =
= 58 degrees
Temperature on ground = 57 degrees
Temperature at 29000 feet = 57 - 58
= -1 degrees
Therefore, temperature at 29000 feet is -1 degrees.
