A rower wanted to determine the speed of a river's current prior to going down a particular section of the river. She released a tracker into the river. The tracker sent her back the following information:   After 5 seconds since the tracker was released into the river the tracker had traveled 5.5 meters. After 10.3 seconds since the tracker was released into the river the tracker had traveled 19.5 meters. Assuming the river was flowing at a constant speed, what was the speed of the current on this section of the river?
