What is the distance traveled by an aircraft flying for 4 hours at a speed of 220 knots?
The aircraft covered 880 nautical miles in 4 hours, which, when converted to regular miles, is approximately 900 miles (Option C).
Calculating the Distance Covered:
Distance (D) = Speed (S) × Time (T)
In this scenario, the speed of the aircraft is given as 220 knots, and the time of flight is 4 hours. By utilizing the formula for distance, we can determine the following:
D = 220 knots × 4 hours = 880 nautical miles
Initially, the answer appears to be 880 miles (Option D). However, it is essential to remember that the question requests the distance in nautical miles, not regular miles.
To convert nautical miles to regular miles, the conversion factor of 1.15078 regular miles to 1 nautical mile is used. By applying this conversion factor, we discover the distance in regular miles:
880 nautical miles × 1.15078 = 1012.69 regular miles
None of the provided answer choices exactly match 1012.69 miles. To identify the closest option, we round it to the nearest value, which is 900 miles (Option C).
Therefore, the final answer is C. 900 miles, representing the distance traveled by the aircraft in nautical miles and the closest approximation when converted to regular miles.
