A car travels from point A to point B in four hours, and then from point B back to point A in six hours. The road between point A and point B is perfectly straight, and the distance between the two points is 240 km. What is the car’s average velocity?

Note : Be careful with speed and velocity, even the formula is same that v = t x ​

If we would like to find the velocity, we must calculate the distance from initial to final, x f ​ − x i ​ = ( d e lt a ) x ,

If we would like to find the speed, we must calculate the total distance that travelled ( x t o t a l ​ .


So, in this question, because it return back to its initial point so (delta)x = 0, so average velocity is 0 m/s.

If you mean average speed, it is 480/10 = 48 kn/h
If you mean average velocity, it is 0/10 = 0 km/h

The average velocity of the car during the round trip from point A to B and back to A is 0 km/h, since the total displacement is zero as it returns to the starting point. The total time taken for the journey is 10 hours.
