- Estimate time and fuel:At 60 mph average, 285 miles takes ~4.75 hours. Fuel: miles ÷ mpg × price/gallon.
- Verify straight-line distance (optional):Use haversine formula for spherical Earth approximation:d = 2R arcsin(√(sin²(Δlat/2) + cos(lat1)cos(lat2)sin²(Δlon/2))),where R = 3,959 miles. Dallas to Galveston: ~260 straight-line miles.
