Where I live it's 20 minutes trip from the city centre. So yep, you're right - adds some time. But not enough to add up to 3x travel time, by far.
This is usually more of a concern for people traveling with lowcost airlines - these cheap out and arrive at another town's airport in many cases. National airlines like Lufthansa will take you much nearer your actual destination.
