If a customer arrives at 7:15 pm, how much time remains before Barney's Burger Barn closes?

• A. 1 hour 45 minutes
• B. 1 hour 30 minutes
• C. 1 hour 15 minutes
• D. 2 hours

Answer: (A)

To find how much time remains, subtract the arrival time from the closing time. Barney’s Burger Barn closes at 9:00 pm, and the customer arrives at 7:15 pm. From 7:15 to 8:00 is 45 minutes, and from 8:00 to 9:00 is 60 minutes. Add them: 45 + 60 = 105 minutes, which is 1 hour and 45 minutes. So, there are 1 hour and 45 minutes left before closing.
