Understanding Speed Conversion
To convert speed from kilometers per hour (km/hr) to meters per second (m/s), we need to use a simple conversion factor.
Conversion Factors
- 1 kilometer = 1000 meters
- 1 hour = 3600 seconds
Conversion Process
To convert 54 km/hr to m/s, follow these steps:
1. Convert kilometers to meters:
- 54 km = 54 * 1000 meters = 54000 meters
2. Convert hours to seconds:
- 1 hour = 3600 seconds
3. Calculate meters per second:
- Speed in m/s = Total meters / Total seconds
- Speed in m/s = 54000 meters / 3600 seconds
Calculating the Result
- Now, performing the division:
- 54000 / 3600 = 15
However, to simplify the calculation, you can divide directly:
- Shortcut Method:
- Convert km/hr to m/s by multiplying by (1000/3600):
- Speed in m/s = 54 * (1000 / 3600) = 54 * (1/3.6) ≈ 15 m/s
Final Result
The correct speed conversion of 54 km/hr is indeed approximately 15 m/s. If the answer provided is '25', please verify the initial speed given, as it may have been incorrectly stated.
This conversion process illustrates how to accurately transform speed from one unit to another using basic arithmetic and understanding of unit conversions.
