Answer:
c
Step-by-step explanation:
For this case we have that the equation of a line in the slope form intersection is given by:
Where:
m: It's the slope
b: It is the cut point with the y axis.
In the green graph we observe that
, then its equation is 
We have the slope of the red line substituting two points:


Thus, the red line has equation
Finally, the blue line is 
Answer:
Green line, y = 5x + 2
Red line, y = 2x + 3
Blue line, y = 3x + 3
Distance southward = 6x = 400, so x=66.66
total distance = 7x+x=8x = 533.33m
