I have a group of lines  (used in Googlemaps display)  based on 2 arrays :

zl = 9 if farthest_proposition.distance_to(origin) < = 25.0
zl = 10 if farthest_proposition.distance_to(origin) <= 15.0
zl = 11 if farthest_proposition.distance_to(origin) <= 10.0
zl = 12 if farthest_proposition.distance_to(origin) <= 5.0
zl = 13 if farthest_proposition.distance_to(origin) < =2.0
zl = 14 if farthest_proposition.distance_to(origin) <= 1.0

how could I replace it the dryest way possible ?

zl = [9, 10, 11, 12, 13, 14]
distance = [1.0, 2.0, 5.0, 10.0, 15.0, 25.0]
farthest_proposition.distance_to(origin) is never > 25 (eliminated before..)
farthest_proposition.distance_to(origin)  can be 0.0, never negative

thanks for yoru suggestions...
