Otto runs 15 miles every day at noon. On average, he finishes at 3:50 p.m. with a standard deviation of 20 minutes. His girlfriend Sien starts 40 minutes later and she runs the 15 miles every day exactly twice twice as fast as Otto. What is the average time that Sien finishes, and what is the standard deviation in minutes when she crosses the finish line?
