Question

Mai spends 7 3/5 hours in school. Her lunch is 30 minutes and switching rooms is another 42 minutes. The rest of her day is spent in 6 classes that are all the same length. How long is each class?

Answer 1

Answer: 1 1/15 hours.
Explanation: 7.36 = total hours of school each day
30 = lunch
42= switching classes
6.22 = 6 classes
1.0366666= 1 class

Answer 2

7 3/5 hours is 456 minutes. Subtracted by the 30 minute lunch and 42 minute class change, you are left with 384 minutes. 384 divided by the 6 classes is 64 minutes each or 1.06667 hours.
