    l=1/2 sheep/hour
    w=1/3
    d=1/6

    1/2+1/3+1/6 = 1 sheep/hour

    So, I get:

    a. 60 minutes

    And I get:
    Lion can eat 1 sheep in 2 hours, or 3 sheep in 6 hours
    Wolf can eat 1 sheep in 3 hours, or 2 sheep in 6 hours
    Dog can eat 1 sheep in 6 hours

    So, together, they can eat 6 sheep in 6 hours, or, 1 sheep in 1 hour.
