SOME 'retarded' people FORGET more than you ever knew. Touche. :^)   >> >I think the swim is MUCH faster than that! Let's see ... > >When I saw your first estimate, as a *swimmer*, I knew and even >FELT that it was far too fast.   It don't take no Einstein or a Nobel Physicist to KNOW that the speed (or velocity) in question is the SUM of the swimming speed AND the speed of the current. So, your *swimmer* experience means zilch since you don't know the speed of the Gulf Stream moving along.   >That's the difference between >someone who has at least a little experience swimming distance >- I used to do 10 miles at a wack - could probably do 3-5 right now >without killing myself and with that current, I could probably do >about 25 or 30! :^)   I could easily do 50 lying on my back and taking a nap while the current does the work. :-)   >> Before Carl sticks HIS head out :^), let me correct my OWN arithmetic >> error of dividing by 24x60 instead of 60x60. > >Good thing you're fast and I have real work to do ! :^)   It took only about 30 secs to make all those corrections, while I was multi-tasking with REAL work ... as making a few grands during those few minutes while I was busy trading real-time on a few hot stocks. :^) > >> >1 mi = 1.609344 km (exactly) = 1609.344 meters (exactly). >> >> So far, so good.

NOW Olympic and world record times are clocked to one THOUSANDTH or a sec. You left out .0016 sec. Harrumpf. :-)   -- Bob. ```
