Find how far away did the impact occur

Reference no: EM13525582

A person lies flat on the sidewalk with her ear to the ground. A limb falls and two distinct sounds are heard, one from the air and the other from the concrete. They are 1.10 sec apart. How far away did the impact occur? (the speed of sound in concrete is 2950 m/s)
