Question 723180: If 4 workers can pack 16 parcels in 8 hours then how many could 8 workers pack in 4 hours?
Answer by josmiceli(19441)   (Show Source):
You can put this solution on YOUR website! Twice as many worker can pack twice as many
parcels in the same amount of time, so
8 workers can pack 32 parcels in 8 hours
In half of that time, the same number of workers
could pack half as many parcels, so
8 workers can pack 16 parcels in 4 hours
