The traditional Moscow-to-Vladivostok route (the Transsiberian railway between two Russian cities) takes seven days to make its 6,152-mile journey.

The same journey by horse wains (carts) took more than 2 years in the 17th century.

Now, it takes about 8 hours to fly the same route.

Estimate how many times faster it is to travel by plane rather than by train, or by wain in the 17th century.
