Question: allison is returning to her camping site across a river...

Question details

2. Allison is returning to her camping site across a riverof width 800m. She plans to swim and then walk there. Her camping site is right on the river bank and is 1000m from the point directly across the river from where she starts her swim. Suppose she can swim at half of the speed of her walking. Find the route that takes the least amount of time for Allison to return. You can assume the river is flowing very slowly so that the speed of the river can be ignored.
