Terese thinks that running various distances throughout the week can make one healthy.  On Monday, she runs 4.2 miles;  Tuesday, 3.8 miles; Wednesday, 3.6 miles; and on Thursday, 4.4 miles.  Determine the average distance Terese runs on each of the days she runs.
The total distance Terese runs is 4.2 + 3.8+4.4 +3.6 = <<4.2+3.8+4.4+3.6=16>>16 miles.
Therefore, she runs with an average distance of 16 /4 = <<16/4=4>>4 miles.
