                 SPEED        TIME          DISTANCE
GOING            r            165/r          165
RETURN           r-22         165/(r-22)     165
DIFFERENCE                      2

The main unknown quantity is the speed GOING TO the destination, r.

Solve this for r, and evaluate the other rate and both times.
