**Damon**, Friday, March 14, 2008 at 9:56amLarry paints L elephants/minute

Moe paints M elephants per minute

Curley paints C elephants per minute

(L + M + C )(3) = 1 elephant

(L) (10) = 1 elephant

(M)(6) = 1 elephant

so

L = 1/10

M = 1/6

(1/10 + 1/6 + C )(3) = 1

3/30 + 5/30 + C = 10/30

C = 2/30 = 1/15 elephants per minute

so

15 minutes per elephant
