Question 687Navigation General

The correct answer is C) 360 yards. The explanation is as follows: 1) The correct answer is C) 360 yards. 2) The distance to the shore can be calculated using the speed of sound, which is approximately 1,100 feet per second. Since the echo of the ship's fog horn is heard 2 seconds after the signal was sounded, the distance to the shore is 1,100 feet per second x 2 seconds = 2,200 feet, which is equal to 360 yards. 3) The other options are incorrect because they do not accurately reflect the distance calculated using the speed of sound and the time delay between the signal and the echo.
