Question

A lion can eat a sheep in 2 hours, a wolf can eat a sheep in 3 hours, and a dog can eat the sheep in 6 hours. How long would it take a lion, a wolf, and a dog all together to eat the poor sheep?

Answer 1

Answer:

1 hour

Step-by-step explanation:

The lion's speed is 1 sheep / 2 hours = ½ sheep/hour.

The wolf's speed is 1 sheep / 3 hours = ⅓ sheep/hour.

The dog's speed is 1 sheep / 6 hours = ⅙ sheep/hour.

Their combined speed is ½ + ⅓ + ⅙ = 1 sheep/hour.

So working together, it will take them 1 hour to eat 1 sheep.
