how fast can sound travel in a second
Speed of sound The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium. In dry air at 0 °C (32 °F), the speed of sound is 331.2 metres per second (1,087 ft/s; 1,192 km/h; 741 mph; 644 kn). At 20 °C (68 °F), the speed of sound is 343 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or a kilometre in 2.91 s or a mile in 4.69 s.
Speed of Sound (song) In an interview, Coldplay vocalist Chris Martin revealed that the song was written in mid-2004 and was inspired by Martin's daughter, Apple, and English alternative rock singer Kate Bush: "That's a song where we were listening to a lot of Kate Bush last summer, and we wanted a song which had a lot of tom-toms in it. I just had my daughter up also, and was kind of feeling in a sense of awe and wonderment, so the song is kind of a Kate Bush song about miracles."[4] The drumbeat of the song was inspired by Bush's 1985 song "Running Up that Hill".[5] In a separate interview, bassist Guy Berryman said: "We were really trying to recreate the drums on that song for this song, and the chords. Some bands are reluctant to admit that they take things from other artists and bands that they listen to and we're shameless in that respect, we don't mind telling."[6]
