Question

How long is the Orange River and Where does it rise and where does it flow into the ocean

Answer 1

It looks like its total length is 2200 km, and the length of it in South Africa is 1800 km.

"The Orange River, South Africa's major river, rises in the Drakensberg in Lesotho, where it is known as the Senqu. From where the river leaves Lesotho, it flows westward for some 2200km to where it finally flows into the Atlantic Ocean at Alexander Bay."

"The Orange River, which forms Namibia's southern border to South Africa, originates in the Drakensberg mountains and covers a distance of 1800 kilometres through South Africa, where it is nowadays called the Gariep river. The river connects with the Atlantic Ocean at Oranjemund."

Answer 2

The length of the Orange River is 2,200 km (1,367 miles).

The source (rise?) is Senqu in the Drakensberg mountains of Lesotho.

It flows into the Atlantic Ocean at Alexander Bay, a town in the extreme north-west of South Africa.

Add.  The Orange River rises in Lesotho where it is known as the Senqu River.
