## 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

Assuming all workers work at the same constant rate:

\[
3 \text{ workers} \times 12 \text{ hours} = 36 \text{ worker-hours}
\]

For 4 workers:

\[
\frac{36 \text{ worker-hours}}{4 \text{ workers}} = 9 \text{ hours}
\]

**Answer: 4 workers would take 9 hours.**
