Raj is training for a swim marathon by swimming from one side of a river, which has a current speed of 3 km/h downstream, to a tree on the other side directly opposite from his starting point. He can swim at a speed of 1.5 km/h in still water. If the river is 4 km wide, how far from the tree will Raj if he swims straight ahead?
