In my neck of the Canadian woods, the default unit of measurement for road distances was the time it took to travel that distance. "How far is it into town? Oh, about twenty minutes." People could deal with kilometers just fine, but you'd have to ask for them explicitly. Often they'd give you a rough guess by converting from minutes, and that's how you could back your way into the unofficial local speed limit (as opposed to what the signs said). At first I assumed this was universal, or at least universal to rural areas, but they don't seem to do it much down here in Texas.
