Answer 1

To convert kilometers per hour to miles per hour, you can use the conversion factor that 1 mile is approximately 1.6 kilometers.

To convert 80 km/h to miles per hour, you can use the following calculation:

\[ \text{Speed in miles per hour} = \frac{\text{Speed in kilometers per hour}}{\text{Kilometers per mile}} \]

So, using 80 km/h:

\[ \text{Speed in miles per hour} = \frac{80}{1.6} \]

Calculating this gives:

\[ \text{Speed in miles per hour} = 50 \text{ mph} \]

So, the correct response is 50 miles per hour.
