There are 11 cars between the middle car and the leftmost car, not counting the middle and leftmost car
So, we have: (left-most car)(11 other cars)(middle car)......
Since there must be the same number of cars to the RIGHT of the middle car, the complete a diagram looks like this:
(left-most car)(11 other cars)(middle car)(11 other cars)(right-most car)
TOTAL number of cars = 1 + 11 + 1 + 11 + 1 = 1
Answer: D
