Question 53

The flight duration is 3 hours and 15 minutes.

The flight from 11:15 AM EST to 1:30 PM CST takes a total of 3 hours and 15 minutes. This accounts for the time zone difference, as CST is one hour behind EST.

A) 2 hr 15 min

This option is incorrect because it underestimates the total travel time. The flight starts at 11:15 AM EST and ends at 1:30 PM CST, which requires accounting for the one-hour difference, making the total duration longer than 2 hours.

B) 3 hr 15 min

This option is correct. The flight departs at 11:15 AM EST and arrives at 1:30 PM CST. To convert the arrival time to EST, you add one hour, making it 2:30 PM EST. The difference between 11:15 AM and 2:30 PM is precisely 3 hours and 15 minutes.

C) 4 hr 15 min

This option is incorrect as it overestimates the flight duration. While it considers a longer duration, the actual calculated difference between the departure and adjusted arrival times does not support this option.

D) 5 hr 15 min

This option is also incorrect. A duration of 5 hours and 15 minutes exceeds the actual time elapsed from the departure at 11:15 AM EST to the arrival at 1:30 PM CST when accounting for the time zone difference.

Conclusion

The correct answer is 3 hours and 15 minutes, as it accurately reflects the time difference between the departure and arrival times after considering the one-hour difference due to the time zones. All other options fail to either accurately calculate the time or misinterpret the time zone impact.
