I made a crystal report in Crystal  X1 with a time dispatched and arrival time.  What formula do I use to get the total difference between each time, and then a TOTAL average at the end of the page or report?

Assuming that your fields are datetime fields, you can use the DateDiff and Average functions to help with this.
 
Create a formula that looks like this:
Average(DateDif('n', {table.DispatchTime}, {table.ArriveTime}))
 
This will give you the average number of minutes difference between the two times.
 
If you want to show this in hours and minutes, you'll need to create a second formula that references the first (which I'll call mailto:%7b@AveMinutes - {@AveMinutes }):
 
ToText(( mailto:%7b@AveMinutes%7d\60 - {@AveMinutes}\60 ), 0) + ":" + ToText(( mailto:%7b@AveMinutes - {@AveMinutes }) mod 60), "00") 
 
Notice that I used a back-slash in the first calculation ('\' instead of '/').  This is the "Integer Divide" operator that gives you the integer part of the division result.
