📐 The Calculation
The Great Wall's total length (including all branches and sections) is approximately 13,171 miles (21,196 km). At 3.1 mph walking speed for 8 hours per day: 13,171 / 3.1 / 8 = 531 days = about 18 months.
Assumptions:
- • Total wall length: 13,171 miles (all sections)
- • Walking speed: 3.1 mph
- • 8 hours of walking per day
- • Many sections are ruined or impassable
