Why Distance Matters in Travel Planning
When planning an intercity trip, total travel time and cost often matter more than raw kilometres. A 400 km drive can stretch to 5–6 hours including traffic and breaks, while the same distance by air takes just one hour.

What Is the Haversine Formula?
The Haversine formula is the mathematical method used to calculate straight-line (as-the-crow-flies) distance. It accounts for Earth's spherical shape and returns the arc length between two coordinate points. Unlike measuring on a flat map, it produces accurate real-world results — especially important over long distances. The straight line between New York and London looks horizontal on a flat map, but in reality it arcs northward over the North Atlantic toward the pole.
