conversations.value: I'm completely lost with this math problem: It takes Bryan 5 minutes to walk from his house to the bus station. Then he rides the bus for 20 minutes. After that, he walks 5 minutes from the bus station to his job. It takes the same amount of time in the morning and the evening. How many hours per year does Bryan spend traveling to and from work, if he works every day?
  Can you give me a hand?

conversations.value: Bryan spends 5+20+5 =30 minutes traveling to work.
  He does this twice a day, so he spends 30*2=60 minutes traveling per day.
  Thus, he spends 60/60=1 hour traveling to and from work every day.
  Thus, he spends 1 hour*365 days =365 hours traveling per year.
