250 km???
45 kmh is 45 kilometers per hour which is about 28 miles per hour
138 mph/222 Kmh
This came off a wikipedia page in related links"European Union (if considered as a single entity)""United states of America I would say. European union is not a single entity. U.S has 212433 kilometers of railroad network which is a lot more than any other countries in the world. see the link below.
If you were travelling at 25 kmh, every hour means you have travelled 25 kilometres. Therefore it would take you 2 hours to travel 50 kilometres.
400 km
400 ÷ 20 = 20 hours (though it is unlikely that the speed would be constant!)
3 hours and 10 minutes!
80 km/h
Three hours 3 x 55 = 165

At 30 kilometers per hour, in each hour you will cover 30 km. So after 3 hours you will have covered 3*30 = 90 kilometers.
Time = Distance/Speed So time = 1550km/120 kmh = 12.9166... hours. This is based on the unrealistic assumption that you can maintain an average speed of 120 kmh for nearly 13 hours - a length of time which will require some fuelling stops, and ideally some comfort stops as well!
