I'm really sorry but I'm afraid that neither is likely.
They may hear the cases together. It depends if they were in similar locations. They may well just deal with them on separate occasions as part of a single justice procedure though.
In terms of sentence, I'm afraid that you don't get to choose the sentence you prefer. You can mitigate of course. The reality though is that they are not going to ban you for contraventions of this kind. The speed is not high enough proportionate to the limit. It would be way outside of the guidelines to do so.
If you have no other active points then they would probably offer the speed awareness course for the first matter.
I'm very sorry but I can only give you truthful information.
Can I clarify anything for you?
