40. A healthcare professional works in a military hospital from 1300 to 2000 hours. How many hours does this healthcare professional work?
Answer: C
The healthcare professional works 7 hours.
The healthcare professional works a total of 7 hours, starting from 1300 hours (1:00 PM) and ending at 2000 hours (8:00 PM).
A) 8 hours
This option is incorrect because the duration from 1300 to 2000 hours is not 8 hours. If calculated, it totals 7 hours, indicating that this option does not accurately reflect the working hours.
B) 11 hours
This option is also incorrect as it significantly overestimates the time worked. The span from 1300 to 2000 hours is less than 11 hours, thus making this choice invalid.
C) 7 hours
This option is correct. The healthcare professional works from 1300 to 2000 hours, which is a total of 7 hours. This time frame is accurately calculated by subtracting the start time from the end time.
D) 12 hours
This option is incorrect because the calculated working hours do not reach 12. The time from 1300 to 2000 hours is clearly less than this, confirming that this choice is not applicable.
Conclusion
In summary, the correct answer is 7 hours, as it accurately reflects the time worked between 1300 and 2000 hours. All other options either underestimate or overestimate the total hours, confirming that they do not align with the actual duration worked.
