There are two simple answers. a) You cannot travel fast enough. You have already consumed the entire two minutes required to average 60 mph over the time it takes to make the trip. b) 90 mph. You will then have travelled an average of 60 mph over the DISTANCE of the trip. There probably are other measures possible as well. -- Mike Huybensz ...decvax!genrad!mit-eddie!cybvax0!mrh
