Decimal calculations (division) and unit conversion. a packaging company can fill a 3-pound box in 0.4 seconds and move to the next box in 0.1 seconds. how many 2-pound boxes can be filled by the machine in 3 hours?

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

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
