To calculate the total duration Andrew worked on Saturday, you need to subtract the starting time from the ending time.
First, let's write the starting and ending times in a 24-hour format:
Starting time: 9:45 am = 9:45
Ending time: 3:40 pm = 15:40
Now, let's convert the times to minutes for easier calculation:
9:45 am = 9*60 + 45 = 585 minutes
3:40 pm = 15*60 + 40 = 940 minutes
To find the duration, subtract the starting time (585) from the ending time (940):
940 - 585 = 355 minutes
Now you can convert the duration from minutes to hours and minutes:
355 minutes = 5 hours + 355 % 60 minutes = 5 hours 55 minutes
Based on this calculation, the correct answer is B) 5 hours 55 minutes.
Therefore, if you got 6 hours 35 minutes as your answer, it seems like you might have made an error during the conversion or calculation. Double-check your calculations to find the mistake.
