Step 2:: Identify the Conversion Factors
- 1 kilometer = $$0.621371$$ miles
To convert kilometers per hour (km/h) to miles per hour (mph), we need to know the conversion factors: - 1 hour remains 1 hour
Step 3:: Set Up the Conversion Calculation
140 \frac{\mathrm{km}}{\mathrm{h}} \times 0.621371 \frac{\mathrm{miles}}{\mathrm{km}}
We'll multiply the given speed by the miles-to-kilometers conversion factor:
Step 4:: Perform the Multiplication
140 \times 0.621371 = 86.99194
Step 5:: Round to a Reasonable Precision
86.99194 \approx 87
Rounding to the nearest whole number:
Final Answer
140 \frac{\mathrm{km}}{\mathrm{h}} = 87 \frac{\mathrm{miles}}{\mathrm{h}}
