To convert the speed of sound from meters per second (m/s) to kilometers per day (km/day), you can use the following steps:
- First, convert meters to kilometers. There are 1,000 meters in a kilometer. So, 1 m = 1/1,000 km = 0.001 km
- Next, convert seconds to days. There are 86,400 seconds in a day (24 hours/day * 60 minutes/hour * 60 seconds/minute). So, 1 s = 1/86,400 day ≈ 0.00001157 day
- Now, multiply the speed of sound in m/s by the conversion factors to get the speed in km/day.
Speed in km/day = (343 m/s) * (0.001 km/m) * (0.00001157 day/s) ≈ 0.003981 km/day
So, the speed of sound in air is approximately 0.003981 kilometers per day (km/day).
