Don't have exact numbers but; This morning it took ~30 min to get to work. The drive would take ~25 min. That yields ~1.2.

My typical ride home is ~25 min. The drive is from 20-25 min. That yields from 1-1.25 depending on traffic.

Yesterday I went the long way home. ~55 min. If I went for a joy ride in my car after work it would be for at least 2 hrs more like 3. Using the 3hrs, rounding 55min to 1 hr that yields 1/3!
