Скорость поезда будет 200/15=40/3 м/с. Перевести в км/ч то будет (40/3)×60×60÷1000=48 км/ч. Длина поезда составит 5×40÷3=66,67 м

The chief rivers of Great Britain are: the Severn6, flowing along the border between England and Wales, tributaries of which include the Avon, famed by Shakespeare; the Thames, which flows eastward to the port of London and some others. The swiftest flowing river in the British Isles is the Spey. Part of the border between Scotland and England is along the lower reaches of the Tweed, near which is made the woolen fabric that bears its name.
There are many lakes in Great Britain. On the northwest side of the Pennine system lies the Lake District, containing the beautiful lakes which give it its name. This district is widely known for its association with the history of English literature and especially with the name of William Wordsworth ( 1770 - 1859), the founder of the Lake School of poets.

The largest cities of Great Britain are: London, Birmingham, Glasgow, Liverpool, Manchester, Sheffield, Bristol, Leeds, and Edinburgh. The most impor¬tant ports are: London, Liverpool, Southampton, Belfast, Glasgow and Cardiff.
Of the four parts which make up Great Britain England is the largest, the industrial and most densely populated part of the United Kingdom. About 50 million people of the population of the UK live in England.
The greatest concentrations of population are in London, Birmingham and northwest industrial cities. The coasts of England are washed by the North Sea, the Irish Sea, the English Channel and the Strait of Dover. No part of England is more than 120 kilometres from the sea. The opening of the Channel Tunnel means Britain's railway network is now linked directly to Europe. Eurostar trains run several times a day from the centre of London to Paris and Brussels.
