From Kapilavastu to Lumbini, how many minutes or hours to reach the end (Lumbini) in a chariot?

I was wondering how could Mahamaya (The Buddha's mother) travel from Kapilavastu to Lumbini, this quickly. It is no wonder that a pregnant Queen could travel in a chariot this far. If it occured, she would have given birth in the chariot. Interestingly some facts about Lumbini which will make you rethink history. http://buddhalivedinsrilanka.blogspot.com/2013/04/lumbini-is-astonishing-fraud-begun-in_7.html So how could she travel this quickly? Maybe Buddha is not an Indian. Also the Lumbini pillar looks fake? Then how does it say she traveled so quickly?
