... The speed of the stream is 3mph. Find the speed of the boat in still water. *This is a Math application of quadratic*

The boat travels 24 miles in 2 hours, the average speed is 12 miles per hour. The speed upstream is 12 - 3 = 9 mph and the speed downstream is 12 + 3 = 15 mph. The average speed is (9 + 15)/2 = 12 mph, same as the speed in still water. Quadratic has nothing to do with it.
