Question

Amy goes to bed 3 hours before midnight and wakes up 7 hours before noon. Between what times does Amy sleep?

Answer 1

Let us find the time when Amy sleeps.

\(\textrm{Amy sleeps 3 hours before midnight.}\)

• The time at midnight is 12:00.
• The time 3 hours before midnight is 9:00.
• The time between noon and midnight is called p.m. or post meridiem.
• So, Amy goes to sleep at 9:00 p.m.

\(\textrm{Amy wakes 7 hours before noon.}\)

• The time at midnight is 12:00.
• The time 7 hours before noon is 12 - 7 = 5:00
• The time between midnight and noon is called a.m. or ante meridiem.
• So, Amy wakes up at 5:00 a.m.

Hence, the correct answer is option B.
