The correct answer is - 25 miles.
The journey/postal/communication relay system established in the Mongol Empire had stations set on approximately 25 miles, though there were variations from around 20 to around 30 miles.
This system was set up because the empire was enormous, so the quick travel of information was key for its functioning and proper organization.
The system, known as yam or ortoo, was very simple but very effective. For the means of travel the horse was the animal that was used, and the Mongols estimated the distance at which a single horse can be giving its maximum in speed, so they put up stations at distances where the horse's speed will start to decline because of exhaustion. The rider of the horse was either giving the message to another rider, or he was taking food and water with him, as well as a new, rested horse, and continued to the other station.

<em>The positive effects of NAFTA on the U.S. economy are an increase in the value of goods and services and an increase of trade with neighbors. </em>
When it was signed in January 1993, the North America Free Trade Agreement between Mexico, Canada, and the United States generated a free trade area for almost 450 million people, according to numbers given by the trade offices from the three countries. The trade has advantages for the U.S. such as the increased of U.S. exports to the other countries, the lower tariffs reduced import taxes and increased economic growth.
Answer:
The stock market crash on October 24, 1929, marked the beginning of the Great Depression in the United States. The day became known as "Black Thursday," Many factors had led to that moment. World War I, changing American ideas of debt and consumption, and an unregulated stock market all played pivotal roles in the economic collapse.
Explanation:
World War I transformed the United States from a relatively small player on the international stage into a center of global finance. American industry had supported the Allied war effort, resulting in a massive influx of cash into the US economy. As the war interrupted existing global trade relationships, the United States stepped in as the main supplier of goods, including weapons and ammunition. These purchases left European countries deeply in debt to the United States.
After the war, the United States began a period of diplomatic isolation. It enacted and raised tariffs in 1921 and 1922 to bolster American industry and keep foreign products out.
In the 1920s (the “Roaring Twenties”) many American consumers, assuming economic prosperity would continue indefinitely, took on large amounts of personal debt, sometimes at extremely high interest rates. Factories depended on these consumers continuing to purchase their goods.
Finally, the stock market, based on Wall Street in New York City, was loosely regulated. There were few rules to ensure invested money was safe. Speculators began to deliberately manipulate stock prices, buying and selling in order to increase their returns. Only a small number of Americans purchased stock directly, most believing that the market values would continue to increase. Many investors, comfortable with debt, bought stocks “on the margin,” using a small personal investment to pay a portion of the actual share value while borrowing the rest from a bank or other lender. They assumed the stock price would rise and they would be able to repay the balance of the loan from their investment profits. This system worked well, until the stock decreased in value.
