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
