The speed of sound in air is about 331 m s⁻¹ at 0 °C and nearly 344 m s⁻¹ at 22 °C. Roughly how much extra time will the sound of thunder take to travel a distance of 1720 m, if the air temperature changes from 22 °C to 0 °C? Assume that all other conditions remain unchanged.

Sound takes 5.0 seconds at 22 °C and approximately 5.196 seconds at 0 °C to cover 1720 meters. Subtracting these values reveals an extra transit time of roughly 0.20 seconds.

    1. At 22 °C, dividing 1720 meters by 344 meters per second gives a transit time of 5.0 seconds. When the temperature drops to 0 °C, dividing 1720 meters by 331 meters per second yields approximately 5.196 seconds. Subtracting the two transit times shows that the sound of thunder takes roughly 0.20 seconds of extra time to arrive.
