Question 934682
When Neil was 2 miles upstream from camp on a canoe trip, he passed a log floating downstream with the current. He paddled upstream for 1 more hour and then returned to camp just as the log arrived. What was the rate of the current?
-------------------
Neil and the log are moving in the same medium, the water, so the time moving away from the log is the same as the time to get back to it.
1 hour away from it and 1 hour back to it.
During that time, the log moved 2 miles.
--> current is 1 mi/hr
