Travel Rates Rule is RT=D.

                 RATE         TIME        DISTANCE
RAIN             r                        252
DRY              r+8                      176
TOTAL                          11


                 RATE         TIME        DISTANCE
RAIN             r            252/r        252
DRY              r+8          176/(r+8)    176
TOTAL                          11
