Cristian wanted to reach home, which was at the center of the sea. He took 15 minutes to maneuver his raft in the opposite direction of the current. On the next day, he took 10 minutes to maneuver his raft in the direction of the current. Find the speed of the raft if the speed of the current is 2 km per hour.
