Speed / Distance / Time calculations are relevant and helpful training. Do them whilst driving - every time you pass a 'milestone' sign on the motorway, work out EXCATLY how long it will take you to get there at your current speed. (tip - 60 mph is 1 mile/minute; work in 60s or fractions of 60 and it becomes easier).
Example - you are doing 80mph and pass a sign that says 40 miles to go. If you were doing 60, it would take 40 mins. At 80, it would take you 60/80*40mins (3/4 of the time). Work out how much time you'd save accelerating to 90, etc. Helps while away a boring motorway journey as well.
Did I say 80mph? Obviously I meant 70......or that you were on an autobahn...
