A math puzzle of Chinese primary school
-
The answer is 200 as already stated. Since the line is moving 100 meters forward and is 100 meters long, then at the end, the last man will be where the first man started. When Batman reaches the front of the line, the line has already moved x meters forward. That means there are 100-x meters back to the start. For Batman to reach the start of the line x meters forward, he has already run 100+x meters. So we have Batman running 100+x meters to get to the start and 100-x to get back to the end. 100+x + 100-x = 200. Tim Smith I'm going to patent thought. I have yet to see any prior art.
Not correct, Tim :-) 241.42 is the right answer. It is a typical quadratic equation problem.

...doesn't anyone read anything besides comic books anymore? ;P Why does a Chinese person have a better grasp of the English language than a bunch of presumably highly educated native english speaking programmers? http://en.wikipedia.org/wiki/Batman_(army)[^]

Yeah, I got my signs reversed. Silly me. The problem is that for the life of me I can't figure out where 5000 came from. *sigh* And I have a BS in Math. But I always sucked at word problems. :laugh: Tim Smith I'm going to patent thought. I have yet to see any prior art.

Clue alert, of course they weren't talking about "Batman". 10 seconds of thought would make that obvious. Thus the whole point of going to the trouble of capitalizing "Batman" to continue the joke. Tim Smith I'm going to patent thought. I have yet to see any prior art.

Do Chinese maths questions usually use the military as subjects. In the UK our questions usually involve trains or shopping ;-) Michael CP Blog [^] Development Blog [^]
how funny - based on your response i wonder about Maths in Australia - perhaps kangaroos ~Alexander Kent

From what I remember at school it was more like 'if there are 300 tourists swimming at Bondi beach and sharks eat 32% of them, how many are left?'
