Question 850Navigation General70% to pass
While navigating in fog off a coastline of steep cliffs, you hear the echo of the ship's fog horn 3 seconds after the signal was sounded. What is the distance to the shore?
AI Explanation
The correct answer is B) 550 yards.
The explanation is as follows:
1) The correct answer is B) 550 yards.
2) The distance to the shore can be calculated using the speed of sound (approximately 1100 feet per second) and the time delay between the sound being produced and the echo being heard. Since the echo was heard 3 seconds after the signal was sounded, the distance to the shore is half the distance the sound traveled, which is 550 yards.
3) The other options are incorrect because they do not accurately reflect the distance based on the time delay provided in the question.
4) Overall, this calculation is a straightforward application of the relationship between distance, time, and speed of sound, which is a key concept tested in US Coast Guard Captain's License Examinations.
