## Homework Statement

A car is moving in a road and its average speed is 40 km/h. Then it moves back in that road by 60 km/h speed. What is the average speed of this car? ( The answer is not 50 km/h )

## Homework Equations

Average speed= d/t

## The Attempt at a Solution

I can't solve this. I get 50 km/h every time. I do this: (60+40)/2

Because I don't have time or distance.

Please Help

Thanks
