  5.  * CALCULATE DISTANCE OF THE SOUND SOURCE
  6.  * _____________________________________________________________________________
  7.  * This program will display a menu that allows the user to select one of four
  8.  * gases. The program will then take the input of seconds it took for the sound 
  9.  * to travel from its source to the location it was dectected. It will then
  10.  * calculate the distance from the sound source to its detected location and
  11.  * display the result in meters.
  12.  * 
  13.  * Computation is based on the formula:
  14.  *  distance = speed * time
  15.  * _____________________________________________________________________________
  16.  * INPUT
  17.  *	 mediumChoice		: The medium the user selects from the menu
  18.  *	 seconds			: The second the sounds traveled through the medium
  19.  * 
  20.  * OUTPUT
  21.  *	 distance	: The distance the medium traveled in meters from the source of
  22.  *				  the sound to the location that the sound was dectected
