Tina is training for a biathlon. To train for the running portion of the race, she runs 8 miles each day over the same course. The first 2 miles of the course is on level ground, while the last 6 miles is downhill. She runs 3 mph slower on level ground than she runs downhill. If the complete course takes 1 hour, how fast does she run on the downhill part of the course?
