1. What is the Distance Equation?

The distance equation (D = S × T) calculates the distance traveled by a boat based on its speed in knots and the time traveled in hours. This fundamental navigation formula is essential for marine navigation and voyage planning.

2. How Does the Calculator Work?

The calculator uses the distance equation:

Where:

• \( D \) — Distance in nautical miles
• \( S \) — Speed in knots (nautical miles per hour)
• \( T \) — Time in hours

Explanation: Since 1 knot equals 1 nautical mile per hour, multiplying speed by time directly gives distance in nautical miles.

3. Importance of Distance Calculation

Details: Accurate distance calculation is crucial for marine navigation, fuel planning, estimating arrival times, and ensuring safe passage planning.

4. Using the Calculator

Tips: Enter speed in knots and time in hours. Both values must be positive numbers. The calculator will compute the distance in nautical miles.

5. Frequently Asked Questions (FAQ)

Q1: What is a knot in navigation?
A: A knot is a unit of speed equal to one nautical mile (1.852 km) per hour, used in maritime and aviation contexts.

Q2: How accurate is this calculation?
A: The calculation is mathematically precise, but actual distance traveled may vary due to currents, wind, and course changes.

Q3: Can I use this for air travel?
A: Yes, the same formula applies for air navigation since aircraft speeds are also measured in knots.

Q4: What's the difference between nautical miles and statute miles?
A: A nautical mile (1,852 meters) is about 15% longer than a statute mile (1,609 meters) and is based on Earth's circumference.

Q5: How do I calculate time if I know distance and speed?
A: Rearrange the formula: Time = Distance / Speed. The calculator can be used by solving for one variable at a time.
