You move from point 1 to point 2, and then from point 2 back to point1, using the identical path. if your average speed from point 1 to point 2 is S1 and the average speed from point 2 back to point 1 is S2. What's the average speed of the entire trip there and back, in terms of S1 and S2.(adsbygoogle = window.adsbygoogle || []).push({});

Wouldn't the average speed going to point 2, and coming back to point 1 sum divded 2, basically (S1+S2)/2 be the average speed for the whole trip?
