Riddle of the Day

[Gizmokid2005]

I drive at an average speed of 30 miles per hour to the railroad station each morning and just catch my train. On a particular morning there was a lot of traffic and at the halfway point I found I had averaged only 15 miles per hour. How fast must I drive for the rest of the way to catch my train?

ANSWER (congrats opnight): You will not make it. Once you hit the halfway point at an average of 15mph, the train is leaving.
