Is my elliptical correct?

So I did a short run on my elliptical today, just to make sure I wasn't completely sedentary today, and here's what my elliptical said:
Ran for 13min41sec, 3.220 meters ran (google says it's 2 miles?), and around 241 calories burned.
I'm 19, 5'3'' and ~232lbs atm.

I'm very skeptical. Is it possible that I burned that much?
Granted I did do this for 25-30 minutes because a lot of the time went into me taking a small break or me slowing down cause I'm verrry unfit. Still, it seems a lot for such a short work-out time.
