The queen of hearts hates white roses. three of her gardeners we're painting them red. they are living playing cards, specifically the two of clubs, five of clubs and the seven if clubs. the two and five working together can paint 16 roses per hour. the five and the seven can paint 18 roses between them in an hour. the two and the seven can combine their labours to paint 10 roses per hour 132 roses need to be painted, so how long would it take to accomplish this if all three playing cards cooperated?
