25 kilometers is roughly 15 1/2 miles, or about a mile in 15 minutes. It would take just over an hour to walk that distance. It's difficult for us to imagine how tiring walking can be, but this simple act of moving one foot after another takes tremendous strength. Your body needs time to recover too! A person who walks regularly does not become exhausted more quickly than someone who goes for a run once in a while. However, the regular walker requires more time to recuperate because he uses different muscles and has more stress on his system. If you want to know how long it takes to walk 25 kilometers, use this formula: Time = Distance / Speed So, it takes 1 hour 30 minutes to walk 25 kilometers. As you can see, this is a very rough estimate. The actual time will vary depending on many factors such as the temperature, the number of stops you make, etc. But this number gives you an idea of how long it takes to walk 25 kilometers. Of course, you can also use cars to calculate how long it takes to drive 25 kilometers. It takes about 35 minutes.
