Miles or Kilometers
The Nile river is the worlds longest river let n stand for the length in miles of the Nile the parana river is 3,030 miles long write an expression to show how much longer the Nile is than the parana
The Huang He, or Yellow River.
Let boat speed = X and current speed = Y Downstream speed = boat speed plus current speed = X + Y Upstream speed = boat speed minus current speed = X -Y Downstream speed = 2 miles divided by 3 minutes = 2/3 miles per minute Upstream speed = 2 miles divided by 15 minutes = 2/15 miles per minute X + Y = 2/3 X - Y = 2/15 add equations 2X = 2/3 + 2/15 = 10/15 + 2/15 = 12/15 = 4/5 divide by 2 X = 4/10 = 2/5 use second equation and find Y as X -Y = 2/15 2/5 - Y = 2/15 6/15 - Y = 2/15 Y = 4/15 = current speed = 0.266 miles per minute
Time = Distance / Speed So it would take you 4160 / 20 hours. You can work that out for yourself.

It has more miles in length than any other river in Europe
That would be the Yellow River, running from the Bayan Har Mountains in western China to the Bohai Sea, about 120 miles south east of Beijing
Since nobody knows the correct answer, it must be several thousand miles per hour.
