Mr. D always followed the advice to conserve energy as he was a conscientious driver. While driving his family Ford one day, he came to a stop sign and noticed that the odometer showed 25952 miles. Observant as he was he recognised that the number was a palindrome. He thought that it will be a long time before a palindromic number happens again. Yet two hours later when he arrived home the odometer showed a new palindrome number.
What was the new palindrome number, and how fast was he travelling in those two hours?
