For a Thanksgiving food drive, volunteers packed 50 boxes of food in 20 minutes. How many boxes did they pack per minute?
A 0.4 minutes/box
B 2.5 boxes/minute
C 0.4 boxes/minute
D 2.5 minutes/box
To find the number of boxes packed per minute, we divide the total number of boxes (50) by the total time in minutes (20).
50 boxes / 20 minutes = 2.5 boxes/minute.
Therefore, the volunteers packed 2.5 boxes per minute. The answer is option B.
