The daily commuter to work for a section of interstate has a mean of 22 minutes and a standard deviation of 2 minutes. In the same community, the mean commute time on a non-interstate route is also normally distributed with a mean of 19.5 minutes and a standard deviation of 4.1 minutes. Joey uses the interstate section to get to work and his commute takes 25 minutes. Toyanda uses the non-interstate route to get to work and her commute takes 25.5 minutes. With this in mind, whose route is longer relative to the distribution of commute times for the respective routes?
