Explanation:
Detailed explanation-1: -The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1, 125 ft/s; 1, 235 km/h; 767 mph; 667 kn), or one kilometre in 2.91 s or one mile in 4.69 s.
Detailed explanation-2: -The speed of sound in air is about 340 m/s.
