Question 7
In one afternoon, a ferry travelled from Island A to Island B and another ferry travelled from Island B to Island A at a different speed. They started at the same time and met for the first time at 3:50 pm. The two ferries continued to their destinations, stopped for 15 minutes before returning. They met again at 4:41 pm. If the two ferries travelled at uniform speeds throughout the whole journey, then at what time did they start their journey?
