Every time the bell rings, each ring lasts for 1 second and there is an
interval of 1 second in between every two rings. At 12 o' clock noon,
the bell rings 12 times. At what time will the 12th ring sound? Specify
the hour, minute, and second.
02 Lisa took 24 seconds to walk directly from the 1st to the 4th floor. Lisa

reaching each floor. How long will it take for Lisa to walk from the 4th to
the 8th floor?
