Final answer:
To convert 48.6 km/h into meters per second, multiply by 1,000 and then divide by 3,600, resulting in approximately 13.5 m/s.
Step-by-step explanation:
To convert a speed from kilometers per hour (km/h) to meters per second (m/s), we use the conversion factor that
1 km = 1,000 meters and 1 hour = 3,600 seconds. Therefore, to convert 48.6 km/h to m/s, we multiply by 1,000 to convert kilometers to meters and then divide by 3,600 to convert hours to seconds.
The calculation is as follows:
48.6 km/h × (1,000 m / 1 km) ÷ (3,600 s / 1 h) = 13.5 m/s (rounded to one decimal place)
Hence, a car traveling at a speed of 48.6 km/h is moving at approximately 13.5 m/s when converted to meters per second.
