Answer:
71 km/h
Step-by-step explanation:
To calculate the average speed, you can use the formula:
Average Speed = Total Distance / Total Time
In your case, the total distance is 230 km and the total time is 3.25 hours:
Average Speed = 230 km / 3.25 h ≈ 70.77 km/h
So, your average speed would need to be approximately 70.77 kilometers per hour to travel 230 kilometers in 3.25 hours.
