About 20 minutes of exercise a day is recommended for children this age, including walking. The word "reasonable" has too many variables such as the child's current health, weight, height, and the distance in question. Without knowing these things you could be talking about the difference between 200 yards and 5 miles.
It's perfectly reasonable to expect 200K or more from any U.S. built vehicle provided that it is maintained properly.

You can expect to get an average of about 175,000 miles out of the 2004 Tahoe. This varies with the type of care the vehicle receives.
With proper maintenance probably 200,000 miles
My '93 has 230,000 miles so far.

You can expect between 200,000 and 300,000 miles from a Honda Odyssey. The bottom line however, is that this will depend on how you look after your car.
