Final answer:
To build a wall of the same size, it will take approximately 24.5 days for 2 obreros working 6 hours a day.
Step-by-step explanation:
Let's calculate the number of work hours required to build the wall based on the given information:
14 obreros working 7 hours a day for 3 days equals:
(14 * 7) * 3 = 294 total work hours
Now, let's calculate how many days it will take 2 obreros working 6 hours a day to build the same wall:
2 obreros working 6 hours a day equals:
2 * 6 = 12 work hours per day
To find the number of days it will take, we divide the total work hours (294) by the work hours per day (12):
294 / 12 = 24.5 days
Therefore, it will take approximately 24.5 days for 2 obreros working 6 hours a day to build a wall of the same size.
