## Prompt

If 3 workers build a wall in 12 hours, how long would 4 workers take to build the same wall working at the same rate? Show your work.

## Response

Four workers would take 9 hours to build the same wall at the same rate.

The total work is first calculated as 3 workers multiplied by 12 hours, which equals 36 worker-hours.  
Dividing the total work by the new number of workers gives the required time:  
\[ \frac{36}{4} = 9 \]  
hours.

What assumptions about worker productivity might change this result in a real-world scenario?
