Question 3527 Deck General

The correct answer is D) 2 hours. The helicopter should be carrying enough fuel to last for the entire round trip, which is 45 minutes each way, plus an additional safety margin. The total duration of the round trip is 45 minutes + 45 minutes = 1 hour and 30 minutes. However, to account for unexpected delays or emergencies, the helicopter should have enough fuel to fly for an additional 30 minutes, which brings the total fuel requirement to 2 hours. The other options are incorrect because they do not provide a sufficient safety margin. Option A) 45 minutes is only enough for the one-way trip, not the round trip. Option B) 1 hour and 15 minutes is not enough to cover the round trip and the additional 30-minute safety margin. Option C) 1 hour and 30 minutes is only enough for the round trip, but does not include the additional safety margin.
