1 mile = 1760 yards 20 * 1.151 = 23.02 23.02 * 1760 = 40,515.2 40,515.2 / 60 = 675.243~ 675.243~ / 60 = 11.2542~ They are traveling 11.25 yards per second I took the number of knots multiplied by the approximate miles per hour equal Then multiplied that by the number of yards in a mile, and then divided that by the number of minutes in an hour, and divided that by the number of seconds in a minute. That is how I got the answer, I hope it helps!
