Speed, or Movement, means relative to the world...not the belt.

My GPS will say I'm going 0 mph if I am on a tread mill that is turning at 4 mph.

If my tread mill MATCHES MY SPEED, it would be turning at ZERO MPH.
You're changing the scenario.

If your moving at 4mph relative to the conveyor, the conveyor thinks you are moving 4mph, regardless of what your GPS says. Therefore, the conveyor will move at -4mph.

If there is someone controlling the conveyor and they are watching a pedometer you are wearing - you are going 4mph to them. So the conveyor stays at -4mph.

If they are WATCHING you - they will stop the conveyor (since by observation, you aren't moving relative to them). But then you will suddenly thrust forward - and they will see they were mistaken on your speed.

Basically - the question is worded poorly. It doesn't say what the speeds are relative to.[/b]
um, relative to the planet...like what speed means.

Although...this DOES clarify WHY so many of you CAN't figure this out.

Speed is a universal term...but, the wrong answer people are confusing Speedometer speed with REAL speed.

Speed is how quickly you cover a distance, say in miles per hour.

If I am going 4 mph, I will be able to cover 4 miles in one hour.

My speed on a tread mill is zero, no mater how fast the TREAD MILL IS GOING. (Assuming I don't have a heart attack, etc...)

My pedometer/speedometer might SAY 4 mph...but it would be tricked into it...

The speed you READ while ON a tread mill is your EQUIVALENT speed, IF IT were NOT a tread mill.

Maybe that's the bone of contention...what speed means in THIS scenario?

If we agree what speed means..for THIS problem...this will all fall into place?
