Yes, but I must ask - why did you say the treadmill was infinitely long? That makes it seem like you can use it in either direction.

"matching speed" means it will go as fast as the wheel, regardless of direction. It still says nothing about the direction of the treadmill. Wow, I edited my last post and there have been like 4 more posts since, so these posts probably don't make much sense... this thread is moving fast ...

Duckshirt- If the plane turned around, the treadmill would just match the wheel's speed. It doesn't matter which way it's facing. It doesn't necessarily say that it will match the speed in the opposite direction. That's probably what mathemagic meant, but it might match the speed in the same direct...

Can you tell me what part of that post you find illogical? I did read it, it was perfectly logical and made sense, and it was correct. However, it did not cover what my point was - the plane can turn around and go in the opposite direction, allowing it to reach the speed it needs to take off. The o...

I did! I even said so in my post (did you read it even?). You've just said something that has been proven to be untrue at least ten times this thread. What has been proven untrue? That if the plane turns around and goes in the other direction, it can't take off? It would go faster than the normal ta...

Yes, of course the plane can still take off. All it has to do is turn around and go the other direction.

Did you even read the thread or just decided to post your uninformed and unbacked opinion? Did you even think about it? Did you even consider once that you might be wrong about it? No, I just misunderstood it (before you posted Ubertaker's long post), thinking the treadmill was moving as fast as th...

Wait, so the treadmill's going backwards, and the wheels are going forward?
Wow, I'm slow. In that case, the plane obviously can't take off.

Yeah, that's what I mean by the wings. The airplanes use the air currents with its wings, not the wheels.

Guh, it's obviously base 34 (meaning x would have to represent 33), so in base ten it would look like:

X - 7 = 43 + 33
So x = 83 in base ten, meaning the solution in their base would be:

X = 1E.

Duh, that was an easy one.
