Step-by-step reasoning process: First find the total distance the potato flies in yards: 200 yards / field * 6 fields = 1200 yards. Then multiply that number by the number of feet per yard to convert it to feet: 1200 yards * 3 feet / yard = 3600 feet. Then divide that number by the dog's speed to find the number of minutes it has to run to fetch the potato: 3600 feet / 400 feet / minute = 9 minutes.
