Two observations were made of a clock at different time:
1st observation:
The hour hand is exactly at a minute mark and the minute hand is six minutes ahead of it.
2nd observation:
The hour hand is exactly on a dissimilar minute mark and the minute hand is seven minutes ahead of it.
Can you find out how much time has passed between the above two observations?
2hours 12 minutes
The minute hand is exactly 6 minutes ahead of hour hand at 1:12 (also hour hand is exactly at minute mark)
The minute hand is exactly 7 minutes ahead of hour hand at 3:24 (also hour hand is exactly at minute mark)
so time elapsed = 3 hr 24 min – 1 hr 12 min
= 2hr 12 min
