Answer 1

In this question, you know that the machine packs
`(2)/(3)` of a box every
`(1)/(2)` of a minute. Since it is constant, you simply have to double the half a minute to a full minute and then also double the rate to get
`(4)/(3)` boxes packed per minute. And
`(4)/(3)` is equal to
`1(1)/(3)`
