  7.  *______________________________________________________________________________
  8.  * This program displays a menu of four gases. The user selects a gas and enters
  9.  * the time it took sound to travel through it. The program then calculates and
  10.  * displays the distance the sound traveled, using each gas's speed of sound.
  11.  * 
  12.  * INPUT
  13.  *	 choice			: Menu selection for the gas (1-4)
  14.  *   seconds        : Time in seconds for sound to travel (0-30)
  15.  * 
  16.  * OUTPUT			: Distance sound traveled, in meters
