To convert the car's speed from kilometers per hour (km/h) to miles per hour (mph), we can use the conversion factor that 1 mile is equal to 1.6 kilometers.

1. Convert the speed from km/h to mph:

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

\[\text { Speed in mph} = \frac { 80 \text { km/h} } { 1.6 \text { km/mile} } \]

\[\text { Speed in mph} = 50 \text { mph} \]

2. Calculate the distance traveled in 2 hours:

\[\text { Distance} = \text { Speed} \times \text { Time} \]

\[\text { Distance} = 50 \text { mph} \times 2 \text { hours} \]

\[\text { Distance} = 100 \text { miles} \]

Therefore, the car's speed is 50 miles per hour, and the car will travel 100 miles in 2 hours.

Supplemental Knowledge:

To convert speed from kilometers per hour (km/h) to miles per hour (mph), we use the conversion factor between kilometers and miles. Given that 1 mile is equal to 1.6 kilometers, the conversion factor is:

\[1 \text { mile} = 1.6 \text { kilometers} \]

To convert km/h to mph, we divide the speed in km/h by the conversion factor.
