Answer: 60 miles per hour
Explanation:
You included no scenario so I will develop a hypothetical that you can reference.
Assuming a car traveled a distance of 450 miles from one place to another in 9 hours with the car travelling 180 of those miles between 6 hours and 9 hours, what was the average speed between those 6 and 9 hours.
The car travelled 180 miles in 6hours - 9 hours. First find out how many hours this is:
= 9 - 6
= 3 hours
Speed = Distance / Time
= 180 / 3 hours
= 60 miles per hour
