Yeah. It's 10:30 for the infantry, so it will almost certainly be less for the RAC. Just keep training and get even fitter, because it'll benefit you and the army and you'll be able to do the job even better than the basic standards.
I thought 10.30 was the required minimum standard time for the run (but I am old and crusty, so could be wrong). Having said that, at your age you can improve those results drastically in a short time with grit and determination.
Try for sub 10 mins on the run and 100+ for sit-ups and pressups. Achieve that and training will be far easier (to pass the required standards).
