Name: ___________________________ PRACTICE TEST 2 SHOW ALL WORK!!! 1. (10 pts.) Derek canoes for 3 hours with a 4-km/h current to reach a campsite. The return trip against the same current took 6 hours. Find how fast Derek can canoe in still water (without a current). Write your solution in a sentence! You must use algebra to solve this problem. If you don’t, you will get 0 points. 2. (10 pts.) Solve by graphing: = - = + 2 8 2 x y y x If you do not graph the lines, you will get 0 points. 1
