Q:a kayaker paddles upstream for 1.5 hours then turns his kayak around and returns to his tent in 1 hour. he travels 3 miles each way. what is the rate of the rivers currents

A:0.5mi/h

B:2mi/h

C:1 mi/h

D:1.5 mi/h

For the first one, it would be a mile every half hour, or a mile and a half every hour. The second one would be 1 mile every twenty minutes. I think it would be safe to say an 1 hour and a half or answer choice "D" for this problem.

Let me now if I can be more of an assistance!
