Convert 80 kilometers per hour to miles per hour.
Understand the Problem
The question is asking us to convert a speed measurement from kilometers per hour (km/h) to miles per hour (mph). To do this, we will use the conversion factor where 1 kilometer is approximately equal to 0.621371 miles.
Answer
The speed in mph is calculated using $ \text{Speed in mph} = X \times 0.621371 $.
Answer for screen readers
The speed in mph can be calculated using the formula $ \text{Speed in mph} = X \times 0.621371 $.
Steps to Solve
- Identify the speed in km/h
Determine the speed you want to convert. Let's say the speed is $X$ km/h.
- Use the conversion factor
To convert kilometers to miles, use the conversion factor: $1 \text{ km} \approx 0.621371 \text{ miles}$. The formula for conversion will be:
$$ \text{Speed in mph} = \text{Speed in km/h} \times 0.621371 $$
- Calculate the speed in mph
Plug in the value of speed $X$ from step 1 into the formula:
$$ \text{Speed in mph} = X \times 0.621371 $$
This will give you the speed in miles per hour.
- Round the answer if necessary
Depending on the required level of precision, you may need to round the final result to a certain number of decimal places.
The speed in mph can be calculated using the formula $ \text{Speed in mph} = X \times 0.621371 $.
More Information
The conversion factor of 0.621371 is widely used for converting kilometers to miles. It's useful in many contexts, especially when traveling or comparing distances in different countries.
Tips
- Ignoring units: Make sure to keep track of the units you are converting from and to.
- Incorrect multiplication: Be careful when multiplying; ensure you multiply the correct value in km/h with the conversion factor.
