One day, Xiao Ming and Xiao Gang went to each other's houses respectively, and they started from their own houses at the same time. Xiao Ming walked 70 meters per minute, and Xiao Gang walked 80 meters per minute. After 10 minutes, the distance between the two of them is 20% of the distance between the two families, so how many meters may the distance between Xiao Ming's house and Xiao Gang's house be?
