The traveled 690 miles in all
Further explanation:
The sum of all three days' miles is our required answer.
Let
m1 be the number of miles drove on first day
m2 be the number of miles drove on second day
m3 be the number of miles drove on third day
and
m be the total number of miles
Then
[tex]m_1=312.8\\m_2=177.2\\m_3=209[/tex]
The total miles are:
[tex]m=m_1+m_2+m_3\\=312.8+177.2+209\\=699\ miles[/tex]
