You can put this solution on YOUR website! What the average is NOT is the average of the
2 speeds, which would be km
-------------------------
The average speed is ALWAYS
( total distance ) / ( total time )
--------------------------
No distance is given, so I can assign any
distance I want, so I will say that the one-way

----------------------
A to B hrs
---------------
B to A hrs
--------------
The total distance is km hrs
