The Yangtze River, in central China, is the longest river in Asia and the third longest river in the world. Beginning from its source in western China, the river flows 3,720 miles to the East China Sea. Its drainage basin covers more than 705,400 square miles. The river's mouth discharges approximately 1,250,000 cubic feet per second. In ancient texts, the Yangtze is called the "Great River," and it is commonly known as Ch'ang Chiang ("Long River") by the Chinese people.
Kellie thought about all the water that flowed from the mouth of the Yangtze each second. She wondered what would happen if all that water could be channeled into a giant hose and discharged in various places around the world. For example, she wondered if the very salty Dead Sea, located between Israel and Jordan, could be drained and brought back to life by refilling it with fresh water from the Yangtze River.
The Dead Sea has a volume of about 8 trillion cubic feet. Suppose that the Dead Sea could be drained and a hose from the Yangtze could be used to refill it. To the nearest hour, how many hours would the giant hose need to be turned on in order to fill the Dead Sea?
