Final answer:

The speed of a car traveling at 33 m/s is equivalent to 118.8 km/h when converted using the factor 1 m/s equals 3.6 km/h. This speed is exceeding the 90 km/h speed limit.

Step-by-step explanation:

Conversion of Speed Units

The task at hand is converting the speed of a car from meters per second (m/s) to kilometers per hour (km/h), and then determining if the car is exceeding the speed limit of 90 km/h. To convert the given speed of 33 m/s to km/h, we use the conversion factor where 1 m/s is equal to 3.6 km/h:

Speed in km/h = Speed in m/s × Conversion factor

Speed in km/h = 33 m/s × 3.6 km/h per m/s

Speed in km/h = 118.8 km/h

Now we compare the converted speed to the speed limit. The car's speed of 118.8 km/h exceeds the speed limit of 90 km/h. Therefore, the car is indeed traveling over the speed limit.
