'Rules' are, only one until the quiz needs your expert help.
1. At 7 am a train moving at 90 kph leaves Birmingham heading for London. At 8 a.m. An identical train travelling at 110 kph leaves London heading for Birmingham. Which train will be closer to London when they meet?d
However, if you consider that the point at which "they meet" is when the 'front' of each train meets (i.e. imagine they are kissing), then technically, the back of the train from London is still closer to London than the one from Birmingham.
This is true. However, it assumes the track is straight. What if the part of the track where they meet is horizontal (west/east)? Then the train further 'south' on the track, presumably the train FROM Birmingham could be closer to London at that point.
