1. The problem is to interpret the time given as "10h 40mn 45s" and understand the number 8 in the context. 2. The time is given in hours, minutes, and seconds: 10 hours, 40 minutes, and 45 seconds. 3. To work with this time, we can convert it all into seconds or minutes if needed. 4. Conversion formulas: - 1 hour = 60 minutes - 1 minute = 60 seconds 5. Convert 10 hours to minutes: $$10 \times 60 = 600$$ minutes. 6. Add the 40 minutes: $$600 + 40 = 640$$ minutes. 7. Convert total minutes to seconds: $$640 \times 60 = 38400$$ seconds. 8. Add the 45 seconds: $$38400 + 45 = 38445$$ seconds. 9. So, the total time in seconds is $$38445$$ seconds. 10. The number 8 next to the vertical and horizontal lines seems unrelated to the time conversion and might be a label or marker. Final answer: The time 10h 40mn 45s equals $$38445$$ seconds.
