To calculate the average speed of the car, we need to use the formula for average speed, which is:
Average Speed = Total Distance / Total Time
In this case, the total distance traveled by the car is 162 miles. The car left point A at 7:30 AM and arrived at point B at 10:30 AM. This means the total time taken for the journey is:
- From 7:30 AM to 10:30 AM is 3 hours.
Now, we can substitute the values into the formula:
Average Speed = 162 miles / 3 hours
Calculating that gives us:
Average Speed = 54 miles per hour
Therefore, the average speed of the car was 54 miles per hour.
