  5.  * COMPUTE TIME OF SOUND
  6.  * ____________________________________________________________
  7.  * This program will display a menu of enviromental mediums and
  8.  * prompt the user for a selction. Then based upon the  users 
  9.  * selction it will compute the time of the sound.   
  10.  * 
  11.  * Computation is based on the formula :
  12.  * time = distance / speed
  13.  * ____________________________________________________________
  14.  * INPUT
  15.  *  choice   : Choice on menu 
  16.  *	distance : Distance of sound traveled 
  17.  *
  18.  * OUTPUT 
  19.  * time      : Time of sound
