Basic Travel Rates Rule RT=D for constant rate R, time T, and D distance.

If you feel the need to use a data table you can. 

                  SPEED     TIME      DISTANCE

UPSTREAM         r-w          3          2202

DOWNSTREAM       r+w          3          2532


Using the basic travel rates rule,


, the system now ready for use of Elimination Method to solve this linear system for r and w; speed without any wind, and the speed of the wind.





To get value for w, subtract the system's members which eliminates r.
