A production crew 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, it can be estimated that the stream is flowing at 1.51 miles per hour. In still water, the explorer can swim at 1.63 miles per hour. At what angle with respect to the shoreline should the crew advise him to swim to travel directly across the stream to his campfire? angle: The temperature of the water is close to freezing. Typically, a human can swim in such water for about 5 min before hypothermia sets in. Calculate the time the explorer spends in the water if the river is 92.1 ft wide. time: min Based on the calculations, should the production crew allow the explorer to swim across the river to his campsite? Yes. The explorer will get cold, but he should be able to make it across the river. No. The explorer will not make it across the river in time, and so the crew will cancel the swim.
