You are measuring a line with a steel tape that has a standardized length equal to 100.000 feet and a weight of 2.25 lb. Three full tape lengths and one partial length were used when making the measurement, resulting in a recorded length of 389.28 ft. The tape was supported at ends only and a pull of 12 pounds was used. What is the distance after being corrected for sag? CORRECT ANSWER IS 389.82ft
