To summarize, the hunter should travel 6.7mi west then toward the cabin. It'll take the hunter 2.97hrs to reach the cabin. Note that Maverick's route would take 3.1hrs.
he should go the entire 8 miles upriver and then head north
at 5mph, it would take 1.6 hours to go up and then another 1.5 hours to go north
