Answer:
The correct answer is 2.5 boxes/minute.
Explanation:
To determine the number of boxes packed per minute, we can divide the total number of boxes packed by the time taken.
In this case, the volunteers packed 50 boxes of food in 20 minutes. To find the number of boxes packed per minute, we divide the total number of boxes (50) by the time taken (20):
Number of boxes packed per minute = Total number of boxes / Time taken
Number of boxes packed per minute = 50 boxes / 20 minutes
Simplifying this calculation, we find that the volunteers packed 2.5 boxes per minute.
