#5) The speed of sound waves depends upon the material through which they are travelling. Sound travels 15 times faster through metal railway tracks; thus, the speed of sound in the train tracks is 5145 m/s. This explains the train trestle seen in the 1986 film, Stand by Me, when one of the boys puts his ear to the train tracks before the band of boys crosses the long train trestle bridge together. What is this speed of sound in inches per minute in the train tracks? There are 2.54 cm per inch, there is 60 seconds in one minute, 5280 ft in one mile, 1609 meters in 1 mile, and 12 inches per foot, more conversions are on your equation sheets. Report answer to 3 sig figs.
