Start at the first time and count the whole hours to the end, one hour at a time. If there's a half hour left over, add 30 minutes.

Watch for: Counting the hour you start on as one of the hours. Forgetting the extra half hour. Losing track when the time goes past 12.
At home: Note when a trip or activity starts and ends, and work out together how long it took.
