- Small animals live in forests that make it the ideal habitat for carnivores.

- It all helps in keeping ecosystems in balance.
Explanation:
The dimension of the book is 1.75 m × 2.25 m. If the book ends up at its initial position. The displacement of the book is equal to zero as the object reaches to its initial position.
If it completes its motion in 23 s, t = 23 s
Total displacement of the book is equal to its perimeter. It is given by :
The net displacement divided by total time taken is called the average velocity of an object. Here, the displacement is 0. So, average velocity is 0.
The average speed of an object is given by :
v = 0.347 m/s
So, the average speed of the book is 0.347 m/s. Hence, this is the required solution.
