Answer:

29454

Step-by-step explanation:

Given in the question,

3 pound box ----  0.4 sec

1 pound box ----   0.4/3

                            2/15 sec

2 pound box ----- 2*2/15

                            4/15 sec

One 2 pound box can be filled and move to next box in 4/15 + 0.1

= 11/30 sec

We know that 1 hour = 3600 seconds

                     3 x 3600 = 10800 seconds

2-pound boxes can be filled by the machine in 3 hours

10800/ 11/30

29454 boxes
