Alvin wants to know what his average paddling rate was for a canoe trip to a campsite. On the way there it took him 10 hours against a river current of 2 km/ hr. On the way back, the same distance took him 6 hours with the same 2 km/hr current. Let r = Alvin's average paddling rate. Express the rates against the current and with the current in terms of r to complete the below table. Distance Rate Time Against the d. current With the current d. Using the information summarized in the above table, set up an equation to solve for Alvin's average paddling rate r. Alvin's average paddling rate was km/hour (If needed, round to 2 decimal places).
