Given : Christie was on a road trip. She traveled 320.95 miles on day one, 231.45 miles on day two, and 120.32 miles on day three.
Then to find the total number of miles she traveled during her three-day trip we need to add them all.
The number of miles she traveled during her three-day trip will be :_
[tex]320.95+231.45+ 120.32=672.72\text{ miles}[/tex]
Therefore, the number of miles she traveled during her three-day trip = [tex]672.72\text{ miles}[/tex]
