4 m/s. A river current has a velocity of 5 km/h relative to the shore, and a boat moves in the same direction as the current at 5 km/h relative to the river. How can the velocity of the boat relative to the shore be calculated?
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.
