## 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

4 workers would take **9 hours** to build the same wall.

## Calculation

The total work required is constant, so worker-hours stay the same:

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

With 4 workers working at the same rate:

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

How long would 6 workers take to build a wall twice as large under the same conditions?
