Given that Boojho saw a cracker burst at night at a distance from his house. He heard the sound of the cracker a little later after seeing the cracker burst. This delay in hearing the sound is because the speed of light $(3\times10^8\ m/s)$ is much larger than the speed of the sound$(340\ m/s)$. So, the light of the burst reaches faster than the sound.
