1. The problem is to convert 0.55 of a day into hours, minutes, and seconds. 2. We know that 1 day = 24 hours. 3. To find the hours, multiply 0.55 by 24: $$0.55 \times 24 = 13.2$$ hours. 4. The integer part 13 is the number of full hours. 5. To find the minutes, take the decimal part 0.2 hours and multiply by 60: $$0.2 \times 60 = 12$$ minutes. 6. There is no decimal part left, so seconds are 0. 7. Therefore, 0.55 days equals 13 hours, 12 minutes, and 0 seconds.
