A farmer has some chickens and rabbits. There are 60 eyes and 100 legs altogether. How many chickens and how many rabbits are there?

20 rabbits, 10 chickens

Step-by-step explanation:

Because chickens and rabbits each have 2 eyes, the number of animals is 60 ÷ 2 = 30.

Let's say that all of the 30 animals are chickens. There would be a total of 30 × 2 = 60 legs.

So the extra (100 – 60) = 40 legs must have come from the rabbits.

Every rabbit has (4 – 2) = 2 more legs than a chicken.

So there are 40 ÷ 2 = 20 rabbits and 30 – 20 = 10 chickens.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
