Question 838139: A car travels 60 miles in one hour, stops, travels 120 km in 1 1/2 hours, stops, and travels 60 km more in half in hour. What is the average speed of this car? Answer by KMST(5328) (Show Source):
You can put this solution on YOUR website! How long did the car stop?
Does the problem really mix miles and kilometers, or is that just a typo?
If those stops were not long, we can calculate as if the car had never stopped.
In that case, the car would have traveled in .
The average speed is kilometers per hour
