Question: A fire crew works a 24-hour shift. If they have a 45-minute break for lunch and a 30-minute break for dinner, how many hours are they actively working?

Answer options:

• 22 hours 45 minutes
• 23 hours 15 minutes ✅ 22 hours 15 minutes
• 23 hours 30 minutes

Correct answer: 22 hours 15 minutes

Explanation: Total break time = 45 minutes + 30 minutes = 75 minutes. Convert 75 minutes to hours and minutes: 1 hour and 15 minutes. Subtract total break time from total shift time: 24 hours - 1 hour 15 minutes = 22 hours 45 minutes. My bad, the calculation for the answer was incorrect. Corrected calculation: 24 hours - (45 minutes + 30 minutes) = 24 hours - 75 minutes. 75 minutes is 1 hour and 15 minutes. So 24 hours - 1 hour 15 minutes = 22 hours 45 minutes. The provided options seem to be off. Let's re-evaluate options. 24 hours = 1440 minutes. 1440 - 75 = 1365 minutes. 1365/60 = 22.75 hours, which is 22 hours and 45 minutes. So, option 0 is correct. Let's adjust options given this. The correct index should be 0.
