With the OD reading total miles, not trip miles. Turn key to on/run position. Push and hold trip button for about 6 seconds or until it displays hours on the OD readout.

Just depends on the daily driving habits. If you are not in city stop and go driving everyday, then 40 miles per hour would be good. If you are a road truck only then could be higher. I am in stop and go traffic everyday. Weekends are where I put most miles, but still can not make up for the daily stop and go. At 71k+ I average about 30 miles per hour.
