1. The problem is to convert 24 hours into seconds. 2. We use the conversion factors: 1 hour = 60 minutes and 1 minute = 60 seconds. 3. First, convert hours to minutes: $$24 \text{ hours} \times 60 = 1440 \text{ minutes}$$ 4. Then convert minutes to seconds: $$1440 \text{ minutes} \times 60 = 86400 \text{ seconds}$$ 5. Therefore, 24 hours is equal to 86400 seconds.
