During a marathon race, a runner's blood flow increases to 5.0 times her resting rate. Her blood's viscosity has dropped to 85.0% of its normal value, and the blood pressure difference across the circulatory system has increased by 50.0%. By what factor has the average radii of her blood vessels increased?
