On the Jensen, if you don't trust the arrival time, you can touch it and switch to remaining distance. You can then do your own math. Other than city traffic situations, I usually just divide by 50 for a good estimate almost no matter what. Even if the speed limit is 65 the math usually doesn't work out that way due to starts, stops, meals and bathroom breaks, toll booths, relatives or work issues calling right when you need to get back on the road, whatever...
