It involves calculating the distance traveled by debris from a supernova explosion as observed from the Galactic center's frame of reference. Given the debris's perspective of the Galactic center approaching at 60,000 km/s and a time duration of 50 seconds in the debris's frame, the goal is to compute the distance traveled in the Galaxy's frame. The correct answer is 3,060,000 km, derived from the formula distance = speed \u00d7 time."}
