Speed, Distance, and Time for Maritime Navigation

This is an introductory-level video about speed, distance, and time calculations used by marine navigators. This is a good lesson for elementary and middle school students just learning algebra to see a practical use of those math skills. It is also good for professional navigators interested in refreshing their skills before exams.
Speed is equal to distance divided by time.
Time is equal to distance divided by speed.
Distance is equal to speed multiplied by time.
Distance is in nautical miles.
Time is in hours.
Speed is in knots (nautical miles per hour).
To convert from hours to minutes, multiply by 60.
To convert from minutes to hours, divide by 60.
Understanding speed, distance, and time calculations is critical for passing Coast Guard chart plotting and navigation exams, as well as becoming a safer boater out there on the water.
If you are preparing for your Coast Guard exams, at any license level, I have a variety of license preparation videos available at www.practicaln...
Happy Navigating!

For good or bad, having seen this on screen, is the acronym STD. I will never forget the formula! All said, solid presentation.

Question: If you have distance & the time of 1.5 its straightforward division. However, if you have the time 5.15 you would have had to covert the 15 minutes by dividing by 60 prior to doing the distance & time division?

[@NavigationTraining]

That's exactly right, thanks!

Great presentation thanks

I am curious. There are 6076.12 feet in a nautical mile. 2000 yards in a nm would equal 6000 feet. Is the other 76.12 feet considered acceptable error?

If your Vessel steer 349T and current sets NxW true at the rate of 2 knots.
At 2215 hrs a light bore 034T and at 2300 hrs the same kight bore 079T Vessel's speed
is 18,5 kts. What is the distance of light at 2300 hrs? pls. help me.
