Question 850Navigation General

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.
