Give the step-by-step reasoning process and then the final answer. A swarm of ants discovered a pile of sugar that spilled from a dropped bag. They begin to harvest it and carry it off to their anthill. Every hour, the ants remove 4 ounces of sugar. The bag of sugar held 24 ounces before it was dropped. After three hours, how many more hours will the ants need to harvest the remaining sugar?
After 3 hours, the ants have removed 4 * 3 = 12 ounces of sugar. There are 24 - 12 = 12 ounces of sugar left. Thus, the ants need 12 / 4 = 3 more hours to harvest the remaining sugar.
The final answer: 3.
