Question

The white river flows at 2mi/h. Phil can paddle his canoe in still water at 8mi/h. If he is 4 miles downstream from a log floating towards him, how long will it take him to reach the log?

Answer 1

4/6 hours (you can round it to how your question wants)

Explanation:

The log is floating towards Phil, so the river is going against Phil. Phil's paddling against the river current. When there was no river current, there would be no force pushing him back, and his speed there is 8mi/h. Since he's going against the river current, his speed is going to decrease by the speed of the river current. So it would be 8-2, which equals 6mi/hour, this is his speed going against the river current. If u use the Time = Distance ÷ Speed formula, then it would be 4 ÷ 6, which is that fraction, and again, you can round it if your teacher wants you to.

hope this helped <3
