30 minutes is about 90,000 meters at the average walking pace in a straight line. For a 60-minute walk at that pace:
30 minutes * 90,000 meters = 900,000 meters, or 9 million kilometers, depending on the route taken.
This calculation assumes an even pace throughout the entire walk and does not account for changes in elevation. If the walk is not a straight line but follows a winding route, the number of minutes will vary based on the terrain.
