Question 964Navigation General70% to pass
While navigating in fog off a coastline of steep cliffs, you hear the echo of the ships fog horn 6 seconds after the signal was sounded. What is the distance to the shore?
AI Explanation
The correct answer is A) 1100 yards.
The reasoning is based on the speed of sound, which is approximately 1100 feet per second. Since the echo was heard 6 seconds after the signal was sounded, the distance to the shore can be calculated by multiplying the speed of sound by half the time elapsed (since the sound had to travel to the shore and back). This results in a distance of 1100 yards to the shore.
The other options are incorrect because they do not accurately reflect the distance based on the given information about the time delay of the echo. Options B, C, and D do not align with the calculation using the speed of sound and the time elapsed.
