A camera operator is filming a nature explorer in the Rocky Mountains. The explorer needs to swim across a river to his campsite. By watching debris flowing down the river, you estimate that the stream is flowing at 0.661 m / s. In still water, he can swim at 0.779 m / s. At what angle, less than 90 degree, with respect to the shoreline would you advise him to swim to travel directly across the stream to his campfire?

Water is near freezing in temperature. Typically a human can only swim in such water for about 300 seconds (or 5 minutes) before hypothermia sets in. Calculate the time the explorer spends in the water if the river is 27.5 meters wide.

Based on your results, what would be your advice to the explorer?
