8 girls can weed a plot of land in 10 days. How many days will 5 girls take to weed the same plot of land, if they work at the same rate.
If 8 girls can weed a plot of land in 10 days, then the total work is equivalent to 8 girls working for 10 days.
8 girls * 10 days = 80 girl-days
If 5 girls were to weed the same plot of land at the same rate, then the number of days they would take can be calculated by:
80 girl-days / 5 girls = 16 days
Therefore, it would take 5 girls 16 days to weed the same plot of land.
