Problem Analysis:
The image shows a cat traveling from
Point K to
Point L along a wavy path. The total path length (distance traveled) is given as
700 meters, and the straight-line distance between
Point K and
Point L is
400 meters. The cat completes this journey in
100 seconds.
We need to answer two questions:
1.
What is the cat’s distance?
2.
What is the cat’s displacement?
Let us solve each question step by step.

Question 10: What is the cat’s distance?
####
Definition of Distance:
- Distance is the total length of the path traveled by an object, regardless of direction.
- It is a scalar quantity (only magnitude, no direction).
####
Given Information:
- The total path length traveled by the cat from
Point K to
Point L is
700 meters.
####
Solution:
The distance traveled by the cat is the total length of the blue wavy line, which is explicitly given as
700 meters.
####
Correct Answer:
$$
\boxed{b) \text{700 meters}}
$$

Question 11: What is the cat’s displacement?
####
Definition of Displacement:
- Displacement is the shortest distance between the initial and final positions of an object, along with the direction from the initial to the final position.
- It is a vector quantity (both magnitude and direction).
####
Given Information:
- The straight-line distance between
Point K and
Point L is
400 meters.
- The direction of travel is from
Point K to
Point L, which is to the
East (as indicated by the compass in the image).
####
Solution:
The displacement of the cat is the straight-line distance from
Point K to
Point L, which is
400 meters to the
East.
####
Correct Answer:
$$
\boxed{c) \text{400 meters to the East}}
$$

Summary of Answers:
1.
Q.10: What is the cat’s distance?
$$
\boxed{b) \text{700 meters}}
$$
2.
Q.11: What is the cat’s displacement?
$$
\boxed{c) \text{400 meters to the East}}
$$
These answers are based on the definitions of distance (total path length) and displacement (shortest straight-line distance with direction).
