 	GENERATE	20,15	; New vehicle enters superhighway (seconds)
 	ASSIGN	1,FN$Passenger	; Assign number of passengers to P1
 	ADVANCE	(60#60),(10#60)	; Travel (minutes to seconds)
 	TERMINATE P1	; Decrease the count by number of passengers
 
 * End time is in seconds. Must be divided by 60.
 * RESULT: 10958 seconds => 182.645 minutes = 3 hr 2 min
