sound travels through cold air at about 1190 kilometers per hour. that means that a sound can travel the length of three football fields in about a second. Some machines, such as jet planes, can travel faster than sound. the world's fastest train can travel 574.8 kilometers per hour. how much faster would it have to go to match the speed of sound in air?
