Such a point could NEVER travel forwards. At best, it would be stationary.

PLEASE EVERY BODY ( IT IS PETROL) THAT IS THE ANSWER.

But some cars have the engine in the back, and the car could speed up because it is going downhill or something, so petrol might not need to flow faster.

I was thinking that the point would move forwards relative to the body of the car. I think you are thinking it would be (at best) stationary relative to the surroundings of the car, I agree.

In fact, thinking about it I believe that even if the car is accelerating under power and the engine is in the front. petrol flowing from the back to the front will not necessarily exceed the backward velocity of the car and so might not be going forward relative to the surroundings.

regardless how fast the car was going backwards,petrol is flowing from the tank at the back of the car(to the front)to the engine which is in the front of the car,ie wot is going forward while the car is going backwards PETROL nothing else can go forward only PETROL

This puzzle is rubbish.

What if there was a butterfly inside the car flying from the back to the front? huh? HUH?

Bowmann is right, but he usually doesn't point out the obvious, and makes fun of those who do.

How can one 'point out the obvious'?

Plonker.

A car travels from A to B at 20mph. It then returns from B to A at 30mph.

What is the average speed?

Oh. Thanks.

Wouldn't any liquid that's in the car be moving forward if the car is moving backwards? Or am I missing something?

Why?
