That is good news for drivers, who are keeping their cars longer than ever before; the average age of all cars on the road is more than 11 years, up from about eight years in 1995, according to Polk research. Still, motorists might not realize the long-term financial benefits of keeping a car for 200,000 miles.

At 2 mph you can already do 20 miles a day. All you have to do is hike for 10 hours. If lightening your pack allows you to walk faster or longer, then you can get to 30 miles per day easily.

Thru-hikers can pick up their permits when they enter the parks. Most hikers hike 8 - 10 miles each day at the beginning of their hike, then slowly work up to 12 - 16 miles per day. Most hikers will eventually have a few 20 - 25 mile days. Occasionally, water is scarce on the trail.

For a decent ballpark, I was taught in scouts: day hiking: 3 miles per hour, + 1 hour for every 1000 feet of elevation climb. backpacking: 2 miles per hour, +1 hour for every 1000 feet of elevation climb. Use the formula, and then take a few walks.

Of course, some cars are driven less than that, but many are driven much more due to long commuting distance. For example, a car manufactured in 2002 with a mileage of about 60,000 is considered fine in 2007. If a car has 110,000 miles or more, it is better to avoid purchasing it.
