What is the time when the hour hand and minute hand overlap completely between 1 and 2 o'clock? Here is the solution. Per a minute, hour hand turns clockwise in 0.5-degree angle. On the other hand, Per a minute, minute hand turns clockwise in 6-degree angle. (So, minute hand is 12 times more faster than hour hand.) At 1:00, hour hand is 30-degree angle ahead of minute hand. And per a minute, 5.5-degree angle catches up. So, 30/5.5 minute after 1 o'clock is the answer. In conclusion, 1:05:(300/11) is the answer. *댓글로 서로 으쌰으쌰해요~^^*
