The current Men’s high school track record for the mile is 3:53, set by Alan Webb back in 2006. The average mile time for a high school senior is 4:22 (262 seconds), with a standard deviation of 6.3 seconds. Paul, a high school senior, runs the mile in 4:19 (259 seconds).

2.) If Brian’s percentile ranking for running the mile is 72%, what is his mile time?
