In a swimming pool, 6 swimmers have to swim such that 3 swimmers start from end A at intervals of 1 minute and the remaining 3 start from end B at intervals of 2 minutes where A and B are opposite ends of the pool & length of the pool is 120 meters. The speed of each swimmer is 20m/min. Whenever two swimmers meet, each of them reverse their direction & start swimming in the opposite direction without any time delay. Each swimmer stops when he reaches one of the ends. If the first swimmer from each start simultaneously, after how many minutes from that time will there be no swimmer in the pool?
