Atoy car is placed at 0 on a number line. it moves 9 cm to the left, then 4 cm to the right, and then 6 cm to the left. what is the total distance the toy car traveled

19 cm

Explanation:

to answer this question, we should remind the difference between distance and displacement:

- the distance covered by an object is the sum of all movements made by the object, regardless of their directions

- the displacement of an object is just the difference in position between its final point and its starting point

Based on these definitions, we can now calculate the distance covered by the car, which has moved 9 cm, then 4 cm and then 6 cm. The distance is just the sum of these values:
