The time it takes to walk 4,000 feet depends on walking speed. On average, a person walks at about 3 to 4 miles per hour, which translates to approximately 4.4 to 5.9 feet per second. Therefore, it would take roughly 15 to 20 minutes to walk 4,000 feet. Individual pace, terrain, and conditions can affect this estimate.

Answer: 4,000,000 ft² = 91.8273 acres
4000 meters = 13,123.4 feet (13,123 feet 45⁄16inches).
1 fathom = 6 feet so 4000 feet = 4000/6 = 666.6667 fathoms.
