conversations.value: Can you give me some step-by-step instructions for this math problem: Keegan is in school for 7.5 hours each day and he is taking 7 classes. He has history and chemistry classes for a combined total of 1.5 hours. How many minutes does Keegan spend in one of his other classes on average?

conversations.value: He has 7-2=5 other classes
  7.5 hours - 1.5 hours = 6 hours
  6 hours = 360 minutes
  360/5 = 72 minutes
  Keegan spends 72 minutes in one of his other classes.
