Answer:
47.5 degrees Farenheit
Step-by-step explanation:
the problem says temperature drops 1.8 deg F for every thousand feet. 3,000 ft of altitude will be achieved so that would to find the amount of deg the temperature will decrease we need to multiply 1.8 X 3, which is 5.4 degrees. subtract 5.4 degrees from 52.9 and you get 47.5 degrees at 3,000 ft of altitude
