Answer:
B
Step-by-step explanation:
Let length of Green Route be g and length of Blue Route be b
From 1st bullet point we can write the equation:
6g+5b = 52
From 2nd bullet, we can write:
12g + 13 b = 119
We can solve for b of the 1st equation as:
[tex]6g+5b = 52\\5b=52-6g\\b=\frac{52-6g}{5}[/tex]
Now we can put this value of b into 2nd equation and solve for g (as shown below):
[tex]12g+13b=119\\12g+13(\frac{52-6g}{5})=119\\12g+\frac{676-78g}{5}=119\\\frac{60g+676-78g}{5}=119\\60g+676-78g=5*119\\60g+676-78g=595\\-18g=-81\\g=\frac{-81}{-18}=4.5[/tex]
Hence, the green route is 4.5 miles, B is right.
