From point A located at the perimeter of a circular forest of diameter 30 km we want to reach the farthest point B of the forest. There is a straight footpath BC passing through the forest. Through the trees we can walk with speed 3 km/h, along the pathway the speed of walking is 5 km/h. Find the shortest possible time needed to reach point B?
