A rather old one but I'll answer it anyway.....

	ignoring which direction the fly is moving at any given time!
	and assuming it can turn around and resume flying at 60mph in
	NO TIME (i.e. an instant )

	the truck is moving at 40mph for 20 miles therefore 1/2 hour.
	a fly moving 60mph for 1/2 hour covers 30 miles! (simple)

	UNTIL REALITY TAKES HOLD.....

	for that I need details of the fly's acceleration and some
	calculus ( which I have forgotten :-> )
