At 6 o'clock in the afternoon, Dongdong started to watch cartoons after dinner. When the cartoons started, he looked at his watch and found that the angle between the hour and minute hands was 110°. Before the news broadcast, the cartoon was over, and Dongdong looked at his watch again, and found that the angle between the hour hand and the minute hand was still 110°. So how many minutes did the animation run in total?
