Question

The speed of sound at sea level is approximately 343 meters per second ((m)/(s)). What is the speed of sound at sea level measured in kilometers per hour ((km)/(h)) ?

Answer 1

The speed of sound at sea level, 343 m/s, converts to approximately 95.3 kilometers per hour when using the conversion rates for meters to kilometers and seconds to hours.

Step-by-step explanation:

To convert the speed of sound from meters per second (m/s) to kilometers per hour (km/h), we multiply by the conversion factors that turn meters into kilometers and seconds into hours. Since 1 kilometer is equivalent to 1000 meters, and 1 hour is equivalent to 3600 seconds, we can perform the following calculation:

Speed of sound in km/h = (speed in m/s) × (1000 m/km) × (1 h/3600 s) = (speed in m/s) × (1000/3600) km/h

For a speed of sound of 343 m/s:

Speed of sound in km/h = 343 m/s × (1000/3600) km/h ≈ 343 × 0.277778 km/h ≈ 95.3 km/h
