  4. * Calculate Speed of Sound
  5. *
  6. * This program calculates the time required for sound to travel
  7. * a given distance through air, water, or steel.
  8. *
  9. * Input:
  10. * Medium selected = choice
  11. * Distance in feet = distance
  12. *
  13. * Output:
  14. * Speed of sound = speed
  15. * Time in seconds = time
