Problem of the Week - Upper Elementary - Jan. 24, 2021 to Jan. 30, 2021

Upper Elementary: 

Question: Tiffany arrived at the airport at 3:50 pm. Her flight was supposed to leave at 5:15 pm, but it was delayed for 2 hours. How long was Tiffany at the airport before her flight left? 

Answer: 3 hours and 25 minutes

Solution: The plane left 2 hours after 5:15PM, which means it left at 7:15PM. It is 25 minutes from 3:50PM to 4:15PM and then it is 3 hours from 4:15PM to 7:15PM, so the total time Tiffany was at the airport was 3 hours and 25 minutes.
