One morning, an earthquake caused Kok Wei's wall clock to stop. Immediately, Kok Wei
telephoned the village chief to inquire about the exact time. "It is 10:00 in the morning,”
said the village chief. When Kok Wei was adjusting the wall clock to the correct time,
another earthquake happened. He accidently adjusted the hour hand to the minute hand
place and ran to a safe place. At night, when Kok Wei returned home, he saw the wall clock
showing 9:00. What is the correct time now?
