Yup, you did. <g>  3600/mph will give you seconds, 3600/seconds gives you
mph.  For example, 75 mph <<>> 48 seconds.  If your wristwatch has a
"tachymeter" scale around the face -- used to be common before they figured
out all sorts of other useless things to put there -- you can read mph
direct off that.  That's the scale that starts at 60 at the top, and goes
counterclockwise to 800 or so.
