MATH HELP!! What is her average speed for the whole race?

A bicycle racer rides from a starting marker to a turnaround marker at 10 m/s. She then rides back along the same route from the turnaround marker to the starting marker at 22 m/s .

I don't know how to find It without knowing anything about how far she biked.. unless you can figure that out from this information??

Update:

It says 16 m/s is wrong...

Update 2:

Just got the answer. It was 14 m/s, but I don't understand why.

    16 m/s.

    The distance is the same going one way and going back the other way. So just add the 2 speed and divide by 2 to get the average.
