Problem 1 : The speed of sound in air at a certain temperature is 340 m/s. Express this speed in kilometers per hour (km/h).
Solution :
To convert meters per second to kilometers per hour, use the conversion factor:
$$[1 \text{ m/s} = 3.6 \text{ km/h}]$$
So, the speed of sound in km/h is:
$$[340 \text{ m/s} \times 3.6 \text{ km/h/m/s} = 1224 \text{ km/h}]$$
