Answer:
At 0° Celsius the speed of sound in U.S. textbooks is 331.3 m/s. At 20° Celsius the speed of sound then is 343.21 m/s, rounded 343 m/s.
Explanation:
The speed of sound is the distance travelled per unit 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 (1,235 km/h; 1,125 ft/s; 767 mph; 667 kn), or a kilometre in 2.9 s or a mile in 4.7 s.
