Adding conditional relations

Given the sign. What would be the best approach to add it? Sign shows two conditions - one based on length (length > 33') and one based on hour intervals (Mo-Fr 11:00-14:00). I know how to add both of them separately, but how to add the info into one single relation? Or, should it even be one single relation or it would be fine to add two separate relations? Many thanks!
