I used to play this game while driving home in my tool truck. Just to pull a figure out of the air. At your old job you spent 12.54 40 hour weeks driving back and forth to work in a year.
116 miles per day/60 mph average= 1.93 hours a day driving
1.93 x 5 days a week x 52 weeks a year divided by a 40 hour work week=12.545 40 hour weeks driving.
