A machine packs boxes at a constant rate of 2/3 of a box every 1/2 minute. What is the number of boxes per minute that the machine packs?
A 1/3
B 3/4
C 1 1/6
D 1 1/3
if it’s 2/3 every half a minute then you do 2/3 times two, or you can just add two onto the numerator. that would give you 4/3 which simplifies to 1 1/3
