Notes
- This is the straight line, and no road follows it. 457 miles is the great-circle distance — what an aircraft approximately flies and what a map measures with a ruler. Driving between the two is always further, typically 15 to 30 percent further across the US road network, and considerably more where a mountain range, a lake or a bay forces a detour. The 525–594 mile figure above applies that usual range; it is not a routed distance and it is not a substitute for one.
- The flight time is block time, not flying time. It allows half an hour for pushback, taxi, climb, descent and approach, then covers the distance at an average ground speed of 500 mph over a track about 4 percent longer than the straight line. That is why a 225-mile hop still takes near an hour: most of it is not cruise.
- Wind makes the two directions different. The jet stream runs west to east across North America, so the westbound leg of any transcontinental route is slower than the eastbound one — often by half an hour on a five-hour flight. The figure here is an average of the two, and a booking site will show you the real scheduled times, which also include the airline's padding.
- Airports are not city centres. These coordinates are the cities themselves. On short hops the drive to and from the airport, plus security, can exceed the flight — which is the arithmetic behind the rule of thumb that under about 300 miles, driving is often faster door to door.
Clarksville, TN to Shreveport, LA
457 miles in a straight line — 735 km — heading south-west from Clarksville.
That works out to roughly 1 h 27 min in the air gate to gate, and somewhere around 525 to 594 miles by road.
Why there are three different numbers here
The straight-line figure is the only exact one. It is the great-circle distance between the two sets of coordinates, and it is what a ruler on a map measures.
Everything else is derived from it and carries assumptions. The road figure applies the usual circuity of the US road network — real roads run 15 to 30 percent longer than the straight line, and much further where terrain intervenes. The flight time assumes half an hour of taxi, climb and descent plus cruise at an average ground speed, and takes no account of which direction you are flying or what the wind is doing.
Read the first number as a fact and the other two as ranges that happen to be printed as numbers.
