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

  1. Identify the speed in km/h

Determine the speed you want to convert. Let's say the speed is $X$ km/h.

  1. 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:

$$ \text{Speed in mph} = \text{Speed in km/h} \times 0.621371 $$

  1. 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.

  1. 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.
