Answer:
2½ boxes
Step-by-step explanation:
From the question given above,
We understood that the machine fills 1/2 box in 1/5 min.
Thus, we can simply obtain the number boxes the machine will fill by doing the following:
The machine fills 1/2 box in 1/5 min.
Therefore, the machine will fill y box in 1 min i.e
y box = (1/2 × 1) ÷ 1/5
y box = 1/2 ÷ 1/5
y box = 1/2 × 5/1
y box = 5/2 = 2½
Therefore, the machine fills 2½ boxes in a minute.
