> The average person in the northeast spends 31 minutes commuting per day [2], for simplicity that's 0.5 hours,* 2 commutes a day, * 5 days a week, * 50 weeks a year (assuming 2 weeks vacation), is 250 hours commuting a week.

You already said it's 31 minutes of commuting per day, so why are you doubling it in your subsequent calculation?

Did you go to the source? It’s 31 minutes commuting to work, most people, I believe, tend to commute back from work too. It could have been more clear, but it’s hardly difficult to understand.
