(If you currently live farther away than what would be considered a reasonable commuting distance, you might mention that you would be willing to locate nearer the companys offices if hired.)
I clocked it on my way here today. I'm exactly 10 miles door-to-door, and it took me 17 minutes to get here.

The ride here today was 40 miles. With moderate traffic, it took almost an hour. I don't mind commuting that far twice a day I like to get an early start on my day.
