8. A cougar is standing in a forest, and scents a deer grazing in the boundary of the forest. The cougar is 3km due East from the edge of the forest, and the deer is 9km North of that point. If the cougar can run through the forest at a rate of 8km/hr, but can run through the field at a rate of 10km/hour, where should the cougar exit the forest in order to reach their prey in the least amount of time?
