I don't see any limit in the problem to time, infact i read it as not giving a rats ass about how long it takes, just how fast his supper r-type gto ricer racer has to go. so i don't see how he has to go faster than the spped of light or something to make the secnod lap, he just need to average 90mph.

last post before sleep... hoping this isn't a joke to bait...
Average speed is defined by distance over time. We have the distance. We have the average speed. Using the formula, we can determine the time.

60 miles an hour means you go a mile a minute, right?

If he's going 30 miles an hour, it takes him 2 minutes to go 1 mile.
So to get it to average out, he'd have to go one mile in -zero- minutes, ie instantaneously.

Also, Darkness? 1/3 DOES equal .3 repeating. "It ends in 3 after an infinite point" or "still contain a remainder of 1/3 * 10^-infinity" are nonsensical.

If there's two things in the math realm I find annoying to deal with, it's infinity and continuity.

I really liked this post though, fun to think about.

Sort of. Kinda. It's the phrasing of the problem.

It's amusing here, but in high school it was frustrating to me. Math teachers misusing terminology and so forth. They think it's okay, but if you point out something like that they think you're trying to get out of doing the math problem and just mark it wrong.

I hated situational problems like that. They're supposed to be teaching you to pick out the information you need to set up a math problem, but Math teachers are not, shall we say, the people who took English or Grammar concentrations.

Yes, and while that is true, and I commend you for noticing these things, you should also be clever enough to realize what the teachers actually wanted to achieve with their questions, and act accordingly.

That doesn't work all the time. Sometimes the teacher makes a grammar mistake that actually changes the structure of the math problem. To portray the concept, think of someone who means to write, "I ran away from a man-eating tiger," but instead writes, "I ran away from a man eating a tiger."

You shouldn't have to unravel a second mystery problem to solve a math problem. The best thing for students to do is write down how they interpreted any word problem, possibly with justification for why they interpreted it that way, and then go from there. The teacher is then better armed to decide if the problem presented war formulated poorley and grade accordingly.

I am pretty sure that a student clever enough to find a grammar problem, is also clever enough to realize the real meaning most of the time. Like in your example; the real intention of the sentence is obvious.

Just because you eat tigers doesn't mean you should expect the rest of us to do the same. Let's clarify the point by recruiting from a classic horror flick. Replace "tiger" with "tomato", and repeat the evaluation.

Of course it depends on the context, which should be given in most cases.

Therein lies the problem. Some teachers actually botch their descriptions so badly that what they describe makes more sense as something other than what they actually mean.
quote:
Train A leaves San Francisco at 8:57 AM with 175 passengers on board, headed towards Washington DC. At 11:03 AM, train B leaves Kansas City, also headed towards Washington DC, carring 1500 tons of cargo.
The above question represents a typical math word problem, excluding the question. Please answer each of the questions below.
quote:
When they meet, which one is closer to Washington DC?
quote:
Which train will arrive at the Virginia border first?
quote:
Which train is moving faster?
quote:
How many passengers are on train B?
quote:
How much wood would a woodchuck chuck if a woodchuck could chuck wood?
quote:
What was the ticket price for this railway?
quote:
Which train has brighter headlights?
Sure this is a straw man argument, but there are teachers who actually do screw up this badly, then refuse to admit it. Some of the questions above are solveable. Others require more information which was not provided. But whichever question the teacher provides, the answer he wants is, "Train A by 57."

If the question contains a small mistake, most people can figure out what the question should mean. If it's a big enough mistake... good luck.

On both sides of the argument.

Basically, as Ja`Deth said, some math teachers have such poor grammar that their phrasing doesn't just make their intentions difficult to discern, but it actually changes the meaning of what they write. The context provided typically does not indicate the teacher's intended meaning any more clearly than the misphrased question itself. Even if the student does figure out what the teacher is asking, doing so can take more time than actually solving the problem (as per Naimah's comment), thus preventing students from finishing their exams.

Exactly correct. There's no grammar mistake or trick involved in the problem. It's just that the answer is counterintuitive.

Oh... got a simpler answer to the 1 mile in zero seconds question.... without the infinate mph answer... which I apologize for. I'll work entirely under your assumptions.

If he travels one mile in zero seconds, he is effectively teleporting.

For the sake of argument, I'll say he can teleport. He can go from point a to point b in zero seconds. He's a super-hero with magic powers.

The problem in this case is that he is on a track that loops. That means geographicly, his end point and his start point are exactly the same.

This means that even if he can teleport, he is screwed. Point a IS point b - so even if he "teleports" he wouldn't have actually moved at all.

As you stated yourself - his time is up already. Even if he goes the speed of light, he'll technicly outshoot his time limit. Any interval of time, no matter how small (unless it's zero), will force him to go past the two minute mark. His only option therefore would be to teleport, and that simply wouldn't work.

Ah...no. I have an extremely hard time doing anything more complicated than algebra and geometry. Always have. I can scrape by in classes like that with a C. It's not lack of doing the work. It's not even a lack of getting help (I've had several tutors). I have a hard time remembering mathematical formulas and the rules for things like sine, cosine, etc. Math is not, nor has ever been an area of aptitude for me.

On the other hand, I'm actually rather good at grammar. It has, in my life, been the onus and boon of my education. I've always had problems picking out the grammatical flaws in things, or at least points of contention in meaning. I always seem to get hung up on those issues in any situation other than casual (internet chatting and forums, for example).
