The Rocket Sled

Your science class is on a field trip to a rocket testing site. A rocket sled traveling 900 meters per second on a track passes the place where you are standing. Suddenly, 270 meters farther down the track the rocket explodes quite unexpectedly. If you hear the sound of the explosion 1.1 seconds after the sled passes by, you can calculate the speed of sound. So do it.
