Answer: B) 7 minutes, 30 seconds per mile.
It takes the slower runner 30/28 minutes longer than the faster runner to complete the race, or 1.071 times longer. Because the faster runner is going at 7 minutes per mile, the second runner is going at 7.5 minutes per mile (1.071 * 7), or 7 minutes and 30 seconds per mile.
