Step-by-Step Calculation and Conversion

To verify or convert this distance yourself:

  1. Identify the route:Input "San Antonio, TX" to "Corpus Christi, TX" into a mapping service for driving miles (144 miles).
  2. Apply the formula for straight-line distance:Use the Haversine formula for spherical Earth approximation:
    Distance = 3959 * acos(sin(lat1)*sin(lat2) + cos(lat1)*cos(lat2)*cos(lon2-lon1))
    Where coordinates are San Antonio (29.4241° N, 98.4936° W) and Corpus Christi (27.8006° N, 97.3964° W), yielding ~130 miles.
  3. Convert to kilometers:Multiply miles by 1.60934.
    • 144 miles × 1.60934 = 231.74 km (driving).
    • 130 miles × 1.60934 = 209.21 km (straight-line).
  4. Estimate travel time:At 60 mph average, 144 miles takes ~2.4 hours.

This process is practical for engineers estimating logistics or students in geography classes.
