Calculating driving time can be tricky because of the various factors that can impact your time like traffic jams, accidents, detours, and so on. A good place to start is going online and using a map service, like MapQuest.com, and enter your starting point and destination point so MapQuest can give you an estimation based on the distance and average speed. This will give you a good starting
. point so you can now factor in how many stops for gasoline, food, and rest stops you plan along the route. As you travel you will want to keep track of the miles you have gone so you can see if your estimated arrival time needs to be adjusted based on your progress. I purchased an inexpensive GPS because my husband and I travel a lot and are known for getting lost. This GPS automatically keeps track of your arrival time and adjusts it based on your progress.
