Problema Solution
if 10 workers can finish 200 items of product in 4 hours, how many workers are needed to finish the same number of items in 2 hours?
Answer provided by our tutors
10 workers can finish 200 items of product in 4 hours
Since the number of workers is inversely proportional to the number of hours, if we double the number of workers the number of hours will decrease 2 times, thus 2*10 = 20 workers will finish the work in 4/2 = 2 hours:
2*10 workers can finish 200 items of product in 4/2 hours
20 workers can finish 200 items of product in 2 hours
