Answer 1

To convert 80 kilometers per hour to miles per hour, you can use the conversion factor that there are approximately 1.6 kilometers in a mile.

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

So,

$$\text{Speed in mph}=\frac{80\text{ km/h}}{1.6}\approx 50\text{ mph}$$

Therefore, the correct response is:

50 miles per hour.
