Mimis math class starts at 9:00 A.M. and lasts for 1 hour and 55 minutes. After math class, Mimi has recess for 15 minutes. What time does Mimis recess end?

1. Start at 9:00 AM
2. 1 hour and 55 minutes of class puts us at 10:55 AM
3. Recess for 15 minutes puts us at 11:10 AM

1. Another way to do this is work in whole hours and minute blocks
2. 9:00 AM, add 1 hour that is 10:00 AM
3. 55 minutes is 5 minutes less than 1 hour
4. So add another hour to 10:00 AM which is 11:00 AM
5. Subtract the 5 minutes is 10:55 AM
6. 15 minutes is 5 minutes + 10 minutes
7. Add 5 minutes to 10:55AM is 11:00
8. 10 minutes added to this is 11:10 AM
