A speed of 10 knots means the boat moves 10 nautical miles per hour. Since 1 nautical mile is 6076 feet, 10 nautical miles are 60760 feet. To convert feet per hour to feet per second, divide by 3600 (the number of seconds in an hour): 60760 feet per hour / 3600 = 16.88 feet per second, which rounds to 17 ft/s.
