What speed do Rhine river barges do?

Rhine river barges typically travel at a speed of 8 to 12 kilometers per hour (5 to 7 miles per hour). This speed is determined by various factors, including river conditions, cargo weight, and the type of barge being used. For example, barges carrying heavy loads or traveling against the current may move slower than those carrying lighter loads or traveling downstream. Additionally, the speed of a barge may also be limited by bridge openings, locks, and other restrictions along the river.
