That's pretty slow for a train though: at 60km/hour average it would have taken just 7 days, 16 days is an average of just 26km/hour!

The answer should be 13 km/h.

13 km/h is a decent jogging speed or a slow bike ride. So for speed, a pony-express of transport bikers can beat boats from China to Europe.
