Answer:
A girls walks 4 steps forward and then 3 steps backward. The girls distance walked is <u>7</u> steps and her displacement is <u>1 </u>steps.
Explanation:
Distance can be defined as the total length of the path traveled from initial position to final position.
Displacement is the shortest distance between initial position and final position. It is difference between final position and initial position.
When a girl walks 4 steps forward and then 3 steps backwards, the distance traveled is: 4 + 3 = 7 steps
Displacement = 4 (forward)-3 (backwards) = +1 (forward)
