Answer 2

Task Completion Time for Brigades

Two brigades completed the task in 4 days, while one brigade completed it independently in 6 days. The time taken by the second brigade is unknown. Let's calculate the average completion time for the task.

Average Completion Time: To find the average completion time, we can use the formula: Average Time = (Total Time Taken) / (Number of Brigades)

Using this formula, we can calculate the average completion time for the task.

Calculation: - Total time taken by the known brigades = 4 days + 4 days + 6 days = 14 days - Number of known brigades = 3

Average Time = 14 days / 3 = 4.67 days

Therefore, the average completion time for the task, based on the known data, is approximately 4.67 days.

This calculation assumes that each brigade's task completion time is independent of the others and that the task is of equal difficulty for all the brigades.

I hope this helps! If you have further questions or need additional assistance, feel free to ask.
