a packing machine fills boxes at a constant rate of 1/2 box every 1/5 of a minute what is the number of boxes per minute that the machine packs

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.
