Question 361317: A goat eats 214 kg. of hay in 60 days, while a cow eats the same amount in 15 days. In how many days could they eat 214 kg. of hay together?

The amount = 214 kg = A
-------
The goat eats A/60 per day
The cow eats A/15 per day
Together, they eat A/60 + A/15 per day = 5A/60 per day
--> 60/5 days to eat 214 kg
= 12 days
