What am i looking at getting?

i was pulled over for speeding in excess of maximum limits which was 94 in a 55. the reason i was driving so fast was because my sisters car had messed up about 40 miles away and i was trying to get there before something bad happened to her. it is my first offense since i got my license and i'm only 19. any advice would help i have to go to court in a month. i was nice to the state trooper but he didn't look to happy to pull me over.
