3. A car travels 432 km in 4.5 hours. What is its average speed?
   A
   B
   C
   D

To find the average speed of the car, you can use the formula: Average Speed = Total Distance / Total Time. Here, the total distance is 432 km, and the total time is 4.5 hours. When you divide 432 km by 4.5 hours, you get an average speed of 96 km/h. So the correct answer is D .

Understanding average speed can enrich your everyday driving experience! By calculating your average speed, you can estimate travel times more accurately. For instance, if you know your average speed is consistent during a journey, you can gauge how long it will take to reach your destination, making planning smoother and more efficient.

If you’re on a road trip, remember to consider factors like traffic and road conditions! A common mistake is miscalculating average speed by forgetting to convert units or misjudging the time spent on breaks. Keeping those factors in mind can save you from arriving late or feeling rushed, turning your journey into a more enjoyable ride!
