Answer: 2 1/3
Step-by-step explanation:
Hi, I got my answer by making 3 groups and splitting 7 into them. When you get 1 left over, you separate it into 3, so everyone gets 1/3 of a piece. Therefore the answer is 2 1/3. :)
-20 + y = 2
y = 22
20 + 3y = 6
y = 14/3
2/3 of a box per 30 secs
2/3 times 2 = 4/3 = 1 1/3
