Determine how far the place you are going is. Google maps, Yahoo maps and Mapquest are all good places to find distance. For example, say you are going to a place two miles away.
Determine how fast you walk. If you do not know, then use the average speed of three miles per hour. In the example, use a speed of three miles per hour.
Divide the distance by the speed. For example, two miles divided by three miles per hour equals 0.667 hours, which is approximately 40 minutes.
