Charlie determined that the distance from her grandmother's house to her house is more than 20,000 feet but less than 26,000 feet. Which of the following could be a reasonable estimate for the distance between the houses?

Any number between 20,001 and 25,999 is a reasonable estimate.

That's 5,998 different numbers! BUT ... even though there are

so many different reasonable estimates, there aren't ANY on the

list you provided with the question.
