It’s phrased very weird, but I believe I have it figured out.
On the map, there distance of the race is 41.9 inches.
So, (41.9)(400) = 16760 feet
        
             
        
        
        
Your answer is x = 3. 
-3(x + 5) = 6 - 3(2x + 4) 
-3x - 15 = 6 -6x - 12
-3x - 15 = -6 - 6x 
-3x + 6x = -6 + 15
3x = -6 + 15 
3x = 9 
x = 3
