Alex is riding in a car that has LEDs at each end. The car passes Jordan, who is standing on the ground 25 m from the car's path, with velocity 0.8c. Flashes from the two LEDs reach Jordan simultaneously, and when he observes them, he observes one to be 3.75 m to his left, and the other to be 3.75 m to his right. According to Alex, how far apart are the LEDs, and what was the delay between their flashes?
