Answer:
Question 8:
Distance: 32cm
Displacement: 2 cm south
Question 9:
Distance: 34cm
Displacement : 2 cm south
Question 10:
Distance: 38 cm
Displacement: 2 cm west
Step-by-step explanation:
Distance is defined as the total length of the path followed when getting from point A to point B.
Displacement is defined as the straight line distance between point A and point B.
Now, the distance the toy car travelled is
![3\operatorname{cm}+8\operatorname{cm}+2\operatorname{cm}+4\operatorname{cm}+3\operatorname{cm}+12\operatorname{cm}=32\operatorname{cm}\text{.}]()
The displacement of the toy is represented in the diagram below:
From the diagram, we see that the displacement of the toy car is 2 cm south .
Question 9.
The distance travelled by the toy car is
![6\operatorname{cm}+7\operatorname{cm}+2\operatorname{cm}+3\operatorname{cm}+6\operatorname{cm}+10\operatorname{cm}=34\operatorname{cm}]()
The displacement of the toy is represented by the diagram below.
As can be seen from the diagram, the displacement of the toy car is 2 cm south .
Question 10.
The distance travelled by the toy car is
![5\operatorname{cm}+10\operatorname{cm}+3\operatorname{cm}+3\operatorname{cm}+2\operatorname{cm}+13\operatorname{cm}+2\operatorname{cm}=38\operatorname{cm}]()
The displacement of the toy car can be found by considering the diagram below.
As can be seen in the diagram above, with all the movement of the toy, it travelled only 2 cm west from its initial position. Hence, the displacement of the toy car is 2 cm west.
