To determine if the car is overspeeding, we need to convert the speed limit from kilometers per hour (km/h) to meters per second (m/s) for a fair comparison.
The speed limit in Cairo road is 100 km/h. To convert this to m/s, we divide by 3.6 since there are 3.6 seconds in an hour:
100 km/h รท 3.6 = 27.78 m/s (approximately)
Therefore, the speed limit on the Cairo road is approximately 27.78 m/s.
If the car is moving at 30 m/s, which is greater than the speed limit of 27.78 m/s, then the car is overspeeding.
