To convert kilometers per hour (kph) to miles per hour (mph), you can use the conversion factor:
1 kilometer = 0.621371 miles.
To convert 100 kph to mph:
\[
100 \text{ kph} \times 0.621371 \text{ mph/km} \approx 62.14 \text{ mph}
\]
Therefore, if the speed limit on the highway is 100 kph, you will exceed the speed limit if you drive faster than approximately 62.14 mph. If your rental car speedometer only reads in mph, you should not exceed 62 mph to stay within the speed limit in Poland.
