Because Germany declared war on Russia On 1st August 1914
The main reason behind the Schlieffen Plan was to ensure that Germany could not be invaded from both the East (Russia) and West (France) simultaneously. The idea was to defeat France swiftly by cutting through Belgium, swiftly deal with the French and then to return to the eastern front to see off Russia who it was reckoned would take longer to mobilise. It was carried out in 1914 long after Count Schlieffen's 'retirement' and was the main reason Britain joined the war as they had an alliance with neutral Belgium to protect her if her neutrality was ever compromised by invasion.
It means... To put into useful action. To get moving. To get ready. To get armed forces ready to fight. So for example: "The United States joined World War One in 1917, but it took them until 1918 to mobilise their troops." "One of Germany's plans for World War One - the Schlieffen Plan - was to conquer France in 6 weeks and only then deal with France's ally - Russia. This was because Russia was expected to take six weeks to mobilise its armed forces fully." Mobilise is spelt Mobilize in US spelling.

Germany had been preparing for war long before 1914. In fact, Germany had started drawing up a plan for war - the Schlieffen Plan - in 1897. It took nine years to finalise, but it was based on the theory that Germany would be at war with France and Russia at the same time. It did not prepare for many of the events that occured in July and August 1914. It was based on the belief that, if the country went to war, Germany would be faced with a war on two frontswith France and Russia.This map shows the war faced by Germany on two frontsThe plan assumed that France was weak and could be beaten quickly, and thatRussia was much stronger, but would take longer to mobilise its army.The plan began to go wrong on 30 July 1914, when Russia mobilised its army, but France did not. Germany was forced to invent a pretext to declare war on France (3 August 1914).Things got worse when Britain declared war on Germany on 4 August 1914 because, in a Treaty of 1839, Britain had promised to defend Belgium.

It took me 3 hours to fly from Germany to Russia, so it is probably about the same.
A flight from Jerusalem, Israel to Moscow, Russia is about 2.5 hours.
