During the drive to the water park the weather caused the family to average 44 miles per hours. After their vacation the weather improved, so they could average 80 miles per hour on the return trip. If the distance each way was equal, and the entire time driving was 6.2 hours, find the distance one way to the water park. </SPAN>\n" );
