200 inches        1 ft
---------------- * ---------- = 16 2/3 feet = 16 ft 8 inches (answer)

Answer 2

So there are 12 inches in a foot. What to do:
1) divide 200 by 12 which is roughly 16.6666 repeating
2) now we know that the average car length is at least 16 feet, but less than 17
3) What I do now, is I take 12 and multiply it by 16 
12 x 16 = 192
4) 200-192 = 8
5) 16 feet and 8 inches is the answer
