The answer to this question depends on how you define “shortest”. If you mean by length, then the Amazon River in South America is the longest river in the world at about 6,400 km (4,000 mi). If you mean by time taken to travel from one end of the river to the other, then the Mississippi River in the United States is the fastest flowing river in the world at an average flow rate of 1.5 m/s (4.6 ft/s).
