Math Problem of the Week - Lower Elementary - Aug. 8, 2021 to Aug. 14, 2021

Lower Elementary: 

Question: Margie and Carrie are twins. Margie was born on December 17 at 11:45 PM, and Carrie was born on December 18 at 12:P07 AM. How much older is Margie than Carrie? 

Answer: 22 minutes older

Solution: The date changes from December 17 to December 18 at 12:00 am. There are 60 minutes in an hour, and 45 minutes is 15 minutes away from 60 minutes, so Margie was born 15 minutes before midnight. 7 minutes later is when Carrie was born, so Margie is 15 minutes + 7 minutes = 22 minutes older than Carrie.
