Question

Answer 1

She takes the dog first, then the llama, then the cat. Easy. 3 trips hope I helped

Answer 2

First take the dog to the other side. Then take the llama across. When you get to where the dog is, drop the llama off and pickup the dog again. Take the dog to where the cat is. Drop off the dog, pick up the cat. Take the cat to the other side of the river, leave it with the llama. Go back, pick up the dog, and continue on! You need 4 round trips, or 8 one-way trips. Hope this helps you!
