To determine the driving time and distance between two cities easily, utilize a GPS device or a website such as Google Maps. Simply enter the starting location and the destination, and the service displays suggested routes, the distance in miles and the estimated driving time.
Remember that driving time is heavily dependent on traffic and driving conditions, such as accidents, construction or weather. A short, half-hour drive under normal conditions can turn into an hour or more in the rain or heavy traffic. Some GPS devices account for these circumstances, and might even display alternative routes to avoid traffic congestion.
