A passenger ship sails from port A to port B. After sailing for 3 hours, the passenger ship is still 235 nautical miles away from port B. At this time, the sailed distance is 94 nautical miles less than half of the whole journey. Based on this calculation, how many hours will it take for the passenger ship to arrive at Port B from now on?
一客轮由甲港开往乙港，航行了3小时后，客轮离乙港还有235海里．这时已航行的路程比全程的一半少94海里．照这样计算，客轮从这时起到达乙港还要多少小时？
