You have to take a better picture
0.83x=182.6
x=182.6/0.83
x=220 miles total trip length.
There are 4 As and 3 Bs, so the ratio of Bs to the total number of As and Bs is ...
... (count of Bs) : (count of As + count of Bs)
... = 3 : (4 + 3)
... = 3 : 7
Expressed as a fraction, this is
... 3/7
0-11/5-17=11/12 is the answer to your question. The work is the equation.
