**JJ**, Friday, February 22, 2013 at 9:55am12/60 = 1/5 of an hour

1 tank can be filled in 1/5 of an hour

your rate is 5 tanks per hour

20/60 = 1/3 of an hour

The tank can be filled in 1/3 of an hour. your rate is 3 tanks per hour

(5 tanks per hour)time + (3 tanks per hour)time = 1 tank filled

5t + 3t = 1

t =1/8 of an hour.

This makes sense because it should take less time to fill the tank if both are working together.
