## 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

3 workers take 12 hours to build the wall, so the total work is **36 worker-hours** \((3 \times 12 = 36)\).  

If 4 workers do the same work at the same rate, the time is:

\[
36 \div 4 = 9
\]

So, **4 workers would take 9 hours**.
