Nautical time speed distance formula. This Distance/Speed/Time Calculator helps solve the fundamental relationship between these three navigation variables, essential for maritime, aviation, and land navigation planning. Time is entered in minutes, speed in knots and distance in nautical miles (the same formula will work for statute miles and kilometres). For speeds of less than 60 knots and when using a log-arithmic scale which increases from left to right, the distance graduation always lies to the left of the time in minutes graduation; the speed in knots graduation always lies to the left of the 60 graduation. Apr 26, 2022 ยท These triangles from Captain John’s Skippers Tips may serve as an easy-to-remember primer, or refresher, on how to determine the basic three factors in coastal navigation: Time, Distance, Speed. All piloting and maneuvering solutions contain three factors: time, speed, and distance. Understanding how to calculate time, speed and distance questions is essential for safe navigation. Enter distance in nautical miles and speed in knots to get exact travel time in hours, minutes, and seconds for precise voyage planning. This is an introductory-level video about speed, distance, and time calculations used by marine navigators. . The use of "60" ensures that time is calculated in minutes rather than in hours and tenths of an hour. If a boat's speed is 5 knots, how far will it go in 3½ hours? D = (S x T) ÷ 60. zlvcf dwnif pgssfso ybdw eqg qfggn qbrc zsqes ydq cniynnj
