When a clock is observed, the hour hand is at a minute mark and the minutes hand is six minutes ahead of it.
When the clock is observed again after some time, the hour hand is precisely on a different minute mark and the minute hand is seven minutes ahead of it.
Can you calculate how much time has elapsed between the two observations?
When the first observation was made, the time was 1:12 and when the second observation was made, the time was 3:24.
Therefore, 2 hours and 12 minutes have passed since the first observation.
