I drove 6835 miles. The majority of miles were driven in seven days. If the mileage was divided equally among the days I was gone, it would amount to 455 miles a day. Of the days, though, three driving days were quite short and five days I did no driving at all.
Note that this is somewhat inexact; I did not leave home with a full tank nor did I return with an empty tank. I did leave and return with similar fuel levels.
