So I very recently, like last week, started running. I started with a mile, and last night hit 3 miles in 30 minutes, on my 4th/5th run.

I was recently told by a doctor's assistant that she can walk a mile in 7.5 minutes.

Now I don't really believe her, especially after this past week.

But my question to you guys is simple: Is a 10 minute mile at least decent for starting out? Is there a mark that is regularly referred to as a a "good" time, that I should be shooting for?

I know I won't hit it overnight, just trying to get a gauge to move forward on.

I guess it is important to know also that I would like to end up running for both a decent distance and a decent time. I don't want to train for sprinting nor marathons, just be able to run a good bit in 30-60 minutes when I can. Thanks all!
