conversations.value: Can you break down the solution for me for this math problem: Kim sleepwalks, to monitor her sleeping hours, she installs a camera in her room. Kim usually goes to sleep at 10 p.m. and wakes up at 6 a.m. She is a sleepwalker. One day, after reviewing the cameras, she finds that she woke up that day and was sleepwalking from 2:15 to 2:38 am.  Also, that day she woke up 5 minutes earlier than usual to go to the bathroom. How many minutes did she sleep on her bed that day?

conversations.value: Out of 24 hours in a day, 10 pm represents 22 hours.
  Until 12 p.m. or 24 hours, Kim slept 24 - 22 = 2 hours.
  In total, Kim usually sleeps 2 + 6 = 8 hours a day.
  In minutes, Kim usually sleeps 8 * 60 = 480 minutes
  Kim was sleepwalking for a total of 38 - 15 = 23 minutes.
  Within her usual sleep routine, Kim was sleepwalking or awake a total of 23 + 5 =28 minutes.
  On that day, Kim slept in her bed for 480 - 28 = 452 minutes.
