Sound travels at different speeds in solids, liquids, and gases. A tap on one end of a 7.2 m solid creates waves traveling through the solid and in the air (vair = 343 m/s). The durations the waves take to arrive on the opposite end of the solid differ by 0.012 s. Find the speed of sound in the solid.
