How to Calculate Distance, Speed, and Time | Basic Navigation Formula
Welcome back to Maritime Academia!
In this lesson, we’ll master one of the most important foundations of navigation — how to calculate Distance, Speed, and Time (DST) using simple formulas that every mariner must know.
Whether you’re a maritime student, a deck cadet, a professional seafarer, or someone curious about how ships measure their travel at sea, this video will guide you step-by-step with clear explanations and sample problems.
What You’ll Learn:
The Distance–Speed–Time Formula
How to find Distance when Speed and Time are known
How to find Speed when Distance and Time are known
How to find Time when Distance and Speed are known
Pro tips on units used in navigation (nautical miles, knots, and hours)
Real-world applications in maritime, aviation, and land travel
Example Problems Covered:
Finding Distance:
If a ship sails at 10 knots for 5 hours, how far does it go?
Finding Speed:
If you cover 60 nautical miles in 6 hours, what’s your speed?
Finding Time:
If you travel 120 nautical miles at 12 knots, how long will it take?
Perfect For:
Maritime Students (BSMT, BSMarE)
Navigators and Deck Cadets
Seafarers refreshing their navigation knowledge
Anyone learning the basic navigation formulas
Formula Recap:
Distance = Speed × Time
Speed = Distance ÷ Time
Time = Distance ÷ Speed
Units to Remember:
• Distance = Nautical Miles (NM)
• Speed = Knots (NM/hour)
• Time = Hours
