## 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

Three workers complete the wall in 12 hours, so the total work is \(3 \times 12 = 36\) worker-hours. At the same rate, 4 workers would take \(36 \div 4 = 9\) hours.

## Work shown

- Total work = \(3 \times 12 = 36\) worker-hours
- Time for 4 workers = \(36 \div 4 = 9\) hours

**Answer: 9 hours**

Would you like a quick rule for solving these worker-rate problems faster?
