Question
The speed of sound is measured to be 342 m/s342 m/s on a certain day. What is this in km/h?
Solution
Step 1: Understand that you need to convert the speed from meters per second (m/s) to kilometers per hour (km/h).
Step 2: Know that 1 kilometer (km) is equal to 1000 meters (m) and 1 hour is equal to 3600 seconds (s).
Step 3: Convert the speed from m/s to km/h using the conversion factors.
The given speed is 342 m/s.
To convert this to km/h, you multiply by the conversion factors:
342 m/s * (1 km/1000 m) * (3600 s/1 h)
Step 4: Simplify the equation. The m units and the s units will cancel out, leaving you with km/h.
342 km/h * (1/1000) * 3600 = 1231.2 km/h
So, the speed of sound on that day was 1231.2 km/h.
