Answer:
x = -6/11
Step-by-step explanation:
-6(-4x + 3) = 2(10x + 3)
-6 * -4x = -24x
-6 * 3 = -18
2 * 10x = 20x
2 * 3 = 6
-24x - 18 = 20x + 6
-20x           -20x
-44x - 18 = 6
+18           +18
-44x = 24
-------   ------ 
  -44      -44
24/-44 = -24/44
-24/44 = -6/22
x = -6/11
 
        
             
        
        
        
Let's assume that the faster car has a 2 mile "head start".
The faster car is 1.2 times faster (48/40) than the slower car.
It will take five 2 mile trips to "catch" the other car.
Five 2 mile trips will take 5 * 40 seconds = 200 seconds.
        
                    
             
        
        
        
I think the answer is C 1 2/3
