    When Joana Mae, Precious Jewels and Molly Anne work together, they finish installing a garden in 3 days. The job could be completed if Joana Mae worked 4 days alone and Molly Anne worked 10 days alone, or if Precious Jewels worked 5 days alone and Molly Anne worked 3 days alone. How many days would it take each worker, alone, to complete the garden?

    We are given, using the word word problem combined formula, that:
    1/j + 1/p + 1/m = 1/3

    However, you state the hours working alone, but then ask how much it would take working alone. I'm confused on the last part. Can you clarify?
