Forestry workers

In the forest is employed 43 laborers planting trees in nurseries. For 6 hour work day would end job in 35 days. After 11 days, 8 laborers go forth?

How many days is needed to complete planting trees in nurseries by others, if they will work 10 hours a day?


x =  17.7 d


43 * 6 * 35 = 11 * 6 * 43 + (43 - 8) * 10 * x

350x = 6192

x = 3096175 ≈ 17.691429
