Step-by-Step Mathematical Derivation

1. Given Input Coordinates:
  • Origin: (40.7128°, -74.006°)
  • Destination: (51.5074°, -0.1278°)
2. Model & Ellipsoid Reference:WGS-84 / Earth Sphere R = 6,371 km
3. Governing Geodesic Formula:Haversine Great Circle Formula
4. Variable Substitution:R = 6,371 km
5. Interpretation & Practical Application:

Straight line geodesic distance is 5570.23 km.

Mathematical Formula

ETA = Current Time + (Distance / Speed)

Overview & Explanation

Calculates arrival times for GPS waypoint navigation based on live or expected speed.

How It Works

  • Divides remaining geodesic distance by speed.

Practical Applications

  • Aviation waypoint check-ins.
  • Outdoor hiking ETA calculations.

Worked Example: 120km at 80 km/h

Calculate travel duration.

Time Division

120 / 80

= 1.5 Hours (1h 30m)
