A class starts at 9:15 AM and ends at 2:05 PM with a 40-minute break. Find the actual teaching time.
Explanation
To find the actual teaching time, we need to subtract the break time from the total time. The class starts at 9:15 AM and ends at 2:05 PM. So, the total time is 4 hours 50 minutes. The break time is 40 minutes. Subtracting the break time from the total time, we get 4 hours 10 minutes. Adding the remaining 15 minutes, we get 4 hours 25 minutes. However, this is not the answer. We need to add the initial 15 minutes to get the actual teaching time which is 5 hours 25 minutes.
