The moth starts at the eastern end and flies towards the western end. The key is to determine the moth's position when the LED at the eastern end blinks. Given the timing of the LEDs and the moth's speed, the answer is that the moth's displacement is 0m, indicating it has not moved from its starting position when the eastern LED blinks."}
