Mark allocation


They allocate a mark for that 40 meters per second and they give you a mark when you said to the right or eastwards. So ladies and gentlemen this is how you score two marks for this question. I'm not really sure guys, if you understood you know what I was trying to explain to you over there ladies and gentlemen. 

The last case ladies and gentlemen, the last case of which it's something that they may ask, let's say this is the car traveling in that direction at 20 meters per second this is the truck traveling in that direction. Let's say it's at 40 meters per second okay. 

So now they are asking maybe what is the speed of this relative to the truck okay. So obviously ladies and gentlemen you know as this car is approaching the truck, the truck is moving away you know two times faster than that okay. 

So obviously this engine it seems as if you know it seems as if this is moving in the opposite direction obviously at 20 meters per second. Let me say at 20 meters per second in which direction? Obviously it seems as if it's moving in the opposite direction which is westward. How is it the case, that it's because if this is the truck and this is the car so you know in this case they are not both moving at 20 meters per second but the other one is moving a bit faster can you see.
