You should use zoomToSpan instead of zoomTo, but you still need to calculate the latitude/longitude (which you'd likely need to do anyway with zoomTo). You should be able to do a google search for information on lat/long calculations. I think you'd basically have to figure out how many feet (or in your case miles) per degree of lat/long, then add that many degrees to the lat/long of the center of your map to get the lat/long of the edge to use in zoomToSpan.
