Obey the speed limit and you won't have to worry anymore.
Ok, now that my adult answer is out of the way...
depending on the speed camera, you have a 50/50 shot. Some of them take a picture from the front and then a series from the rear to catch the car as it moves away, but those ones are fairly rare, from what I understand. Your best bet will be to save your money to pay off a ticket if it comes in, and be prepared to beg and plead for mercy to your parents. If you do end up getting a ticket, go to court with it wearing a suit and address the judge as "your honor" and be respectful, and it will most likely get thrown out.
Even the judge was a young speed demon at some point, and many of them remember it fondly if you come to them respectfully.
