A person sees a heavy stone strike the concrete pavement. A, moment later two sounds are heard from the impact: one travels in the air and the other in concrete, and they are 1.07s apart. How far away did the impact occur? Take the speed of sound in concrete as 2.95x103 m/s and give your answer in km??
