Irene Posted September 20, 2014 Report Share Posted September 20, 2014 ..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?

Alan2273 Posted September 20, 2014 Report Share Posted September 20, 2014 When they meet they must be the same distance from London, only when one has passed the other could the distance be different. Quote Link to comment Share on other sites More sharing options...

Absolutely correct! When they meet they will be on the same spot. ;) Quote Link to comment Share on other sites More sharing options...
