Answer 1

Keep in mind that the earth on which you are standing **is moving** from west to east at a high speed. If you shot a gun and the bullet’s speed was independent on the vehicle’s speed (the earth in this case), that would mean that the bullet would travel at a different speed depending on whether you’d shoot towards the east or towards the west, which is obviously not the case.
