Get some balls and talk to her before you get tree'd. She doesn't have to like you. You might not like her when you get to know her. But you'll never find out until you do.
No problem sir! No better place to do it than here I found!
Anyway. Like the guys above have said, just man up and talk to her.
Talk to her about the dragstrip, the next meet at it or whatever mate, and if you get into a conversation ask her if she would like to go out sometime.
At your (and her age) the worst thing she will say is no. Time is on your side mate, if you think she's worth an effort then go right ahead and try it with her.
EDIT: Including the advice below, just remember, you are of a real young age. Your body and your moods are going to change and keep changing for the next few years. While it never hurts trying, she may still be going through the same phase.
I'm 15, and my girlfriend and I will hit a year in a little over a month. You just have to be responsible, and not go for the girl that drools everytime she sees a set of abs or hears a funny joke/flirty comment.
OP, just go up and make a (tasteful, please be tasteful) joke. Two good rules of thumb: make her laugh (see: tastefully) and don't treat her like one of the guys. Make her feel as if she's a little different than everyone else, but be discreet about it. 👍

Another thing I forgot to mention; She lives 90 miles away.
You can try, and the worst thing she can say is "no". "No" also means that she's not interested, and that she'll get mad if you continue. Rejection might make you sad, but remember; life goes on, and you'll eventually find someone.
