Kinematics An angler sets out upstream from Metaline Falls on the Pend Oreille River. His small boat, powered by an outboard motor, travels at a constant speed v in still water. The water flows at a lower constant speed vw. After he travels upstream for 2.03 km, his ice chest falls out of the boat. He notices that the chest is missing only after he has gone upstream for another 17.8 minutes. At that point, he turns around and heads back downstream, all the time, traveling at the same speed relative to the water. He catches up with the floating ice chest just as it is about to go over the falls at his starting point. How fast is the river flowing? ______ km/h

An angler sets out upstream from Metaline Falls on the Pend Oreille River. His small boat, powered by an outboard motor, travels at a constant speed v in still water. The water flows at a lower constant speed vw. After he travels upstream for 2.03 km, his ice chest falls out of the boat. He notices that the chest is missing only after he has gone upstream for another 17.8 minutes. At that point, he turns around and heads back downstream, all the time, traveling at the same speed relative to the water. He catches up with the floating ice chest just as it is about to go over the falls at his starting point. How fast is the river flowing?
______ km/h
