Yeah, there are a LOT of variables, but 60-100 miles is probably a good range.
FM stations (because of their higher frequency and different modulation) tend to need more power for distance, but do work better in city environments where you're always going under freeways and through tunnels, etc.
But AM stations (which broadcast at very low frequencies) do broadcast farther, just don't penetrate as well.
