Cam used voice commands on his phone to call his friend, Tina, who was studying squirrels in a different part of the park. She planned to run and help him but knew she can only sprint full speed for 300 meters before she loses all energy and passes out. She saw on the map that the coordinates for his tree were at the (250, 50) point and she was currently in the squirrel area at the point (100, 400).
