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