Don't listen to the people immediately above me, either the one saying you're going to quit and should go to your state school, or the one saying to raise your mileage to 50.
Your mile time is significantly better than your 2 mile time, which makes sense, given that your mileage is so low. However, it sounds like you ran that time in December and ran the 2 mile time in the spring. That would indicate that you've improved since the spring, which is good. Keep running and enjoying the sport, hopefully get in contact with college coaches, and you should be ok. It would be good to stay on the upper end of your team's mileage range, and maybe get up to 25-30 miles per week (carefully!) if you can, but don't strain relations with your current coach or anything.
You have the times to run for a D3 school, and it sounds like the talent to turn out to be a significant performer once you adjust to college training. I don't think you would be able to run for a D1 or D2 school. Don't pick a school just based on where you can run, though! Choose your academics first, and where you feel like you'd be happy if you couldn't run, and then factor in running. I don't think you're quite fast enough to be recruited, but you have about a year to go until actual recruiting helps or doesn't help--a year in which you can still improve a lot.
