Answer:
Step-by-step explanation:
1.In the rainy season the width of the river extends to around 25 miles. To put that figure into perspective, if you could walk across the river it would take you about 8 hours to get from one side to the other! Even the Nile River at its widest only measures around 4.6 miles.

2.Yangtze River, Chinese (Pinyin) Chang Jiang or (Wade-Giles romanization) Ch’ang Chiang, longest river in both China and Asia and third longest river in the world, with a length of 3,915 miles (6,300 kilometres). Its basin, extending for some 2,000 miles (3,200 km) from west to east and for more than 600 miles (1,000 km) from north to south, drains an area of 698,265 square miles (1,808,500 square km). so longer then 41 days may be like 51 days..

3.The Mississippi River is the second longest river in North America, flowing 2,350 miles from its source at Lake Itasca through the center of the continental United States to the Gulf of Mexico. The Missouri River, a tributary of the Mississippi River, is about 100 miles longer. Some describe the Mississippi River as being the third longest river system in the world, if the length of Missouri and Ohio Rivers are added to the Mississippi's main stem.
When compared to other world rivers, the Mississippi-Missouri River combination ranks fourth in length (3,710 miles/5,970km) following the Nile (4,160 miles/6,693km), the Amazon (4,000 miles/6,436km), and the Yangtze Rivers (3,964 miles/6,378km). The reported length of a river may increase or decrease as deposition or erosion occurs at its delta, or as meanders are created or cutoff.

Wigth..As a result, different lengths may be reported depending upon the year or measurement method. The staff of Itasca State Park at the Mississippi's headwaters suggest the main stem of the river is 2,552 miles long. The US Geologic Survey has published a number of 2,300 miles, the EPA says it is 2,320 miles long, and the Mississippi National River and Recreation Area suggests the river's length is 2,350 miles.
At Lake Itasca, the river is between 20 and 30 feet wide, the narrowest stretch for its entire length. The widest part of the Mississippi can be found at Lake Winnibigoshish near Bena, MN, where it is wider than 11 miles. The widest navigable section in the shipping channel of the Mississippi is Lake Pepin, where the channel is approximately 2 miles wide.

Speed.At the headwaters of the Mississippi, the average surface speed of the water is about 1.2 miles per hour - roughly one-half as fast as people walk. At New Orleans the river flows at about three miles per hour. But the speed changes as water levels rise or fall and where the river widens, narrows, becomes more shallow or some combination of these factors. It takes about three months for water that leaves Lake Itasca, the river's source, to reach the Gulf of Mexico.
