Ah yes.

I thought and thought and thought......and still didn't get it!

You're thinking too much. I only thought, and that seemed to work.

18. I have a meadow in Zambia with three animals, a zebra, a gazelle and a wildebeest. When the zebra and gazelle graze together, all the grass is gone in 45 days. When the zebra and wildebeest graze together, all the grass is gone in 60 days. When the zebra grazes alone there is no more grass after 90 days. When the gazelle and wildebeest graze together the grass is also gone after 90 days. For how long can all three graze together before the grass is gone? 36 days (see proof below)

19. What connection links these pictures: Servants in Downton Abbey (Hughes; Carson; Bates; Barrow; Daisy)

20. Unscramble the two connected words : A A D E E H I N N P P T V Y ADVENT & EPIPHANY

Maths answer in full: The zebra, the gazelle, and the wildebeest eat grass with a constant speed (amount per day): v1 for the zebra, v2 for the gazelle, v3 for the wildebeest.
The grass grows with a constant amount per day (k).
The amount of grass at the beginning is h.
There is given:
When the zebra and the gazelle graze on the field together, there is no grass left after 45 days. Therefore, h-45x(v1+v2-k) = 0, so v1+v2-k = h/45 = 4xh/180.
When the zebra and the wildebeest graze on the field together, there is no grass left after 60 days. Therefore, h-60x(v1+v3-k) = 0, so v1+v3-k = h/60 = 3xh/180.
When the zebra grazes on the field alone, there is no grass left after 90 days. Therefore, h-90x(v1-k) = 0, so v1-k = h/90 = 2xh/180.
When the gazelle and the wildebeest graze on the field together, there is also no grass left after 90 days. Therefore, h-90x(v2+v3-k) = 0, so v2+v3-k = h/90 = 2xh/180.
From this follows:
v1 = 3 x h/180,
v2 = 2 x h/180,
v3 = 1 x h/180,
k = 1 x h/180.

Then holds for the time t that the three animals can graze together: h-tx(v1+v2+v3-k) = 0, so t = h/(v1+v2+v3-k) = h/(3xh/180+2xh/180+1xh/180-1xh/180) = 36. The three animals can graze together for 36 days.
