If five farmers can finish planting rice in 12 days, how many days will it take for 3 farmers to finish it?

5 farmers * 12 days = 60 farmer-days needed to plant the rice

if only 3 farmers ... 60 farmer days / 3 farmers = 20 days

Did you know?

Did you know that the number of workers can impact the time needed to complete a task? In agricultural fields, like planting rice, it is interesting to note that more workers could reduce the time required. For example, if five farmers can finish planting rice in 12 days, it indicates that the work rate of each farmer is 1/12 of the total work. Now, let's consider an intriguing scenario: If only three farmers were assigned this task, would it take longer or shorter to complete? Curiously, it would take a bit longer, as the work rate per farmer remains constant. Hence, with three farmers, it would take around 20 days for them to finish planting the rice. Remember, teamwork can significantly affect the overall efficiency and duration of completing any task!
