Final answer:

The rate of descent of the hot air balloon is 27.5 feet per minute.

Step-by-step explanation:

To find the rate of descent of the hot air balloon, we need to calculate the difference in elevation and divide it by the time taken. The difference in elevation is 4,770 feet - 3,340 feet = 1,430 feet. The time taken is 52 minutes. So, the rate of descent is 1,430 feet / 52 minutes = 27.5 feet per minute.

Rate of descent = (Initial Elevation - Final Elevation) / Time

Rate of descent = (4,770 feet - 3,340 feet) / 52 minutes

Rate of descent = 1,430 feet / 52 minutes

Rate of descent = 27.5 feet per minute

Therefore, the correct answer is

A) 65 feet per minute
