Answer 1

To convert from kilometers per hour (km/h) to miles per hour (mph), you can use the conversion factor that 1 mile is approximately 1.6 kilometers.

So, to convert 80 km/h to mph, you can use the following calculation:

\[
\text{Speed in mph} = \frac{\text{Speed in km/h}}{1.6}
\]

\[
\text{Speed in mph} = \frac{80}{1.6} \approx 50
\]

Therefore, 80 km/h is approximately 50 mph. The correct response is 50 miles per hour.
