Question
Riya starts at – 0.7 m from the origin. She walks 3.3 m to the left, and then 4 m to the right. What is Riya’s final position in meters? (Note: If you get a negative value, mark your response with a minus sign)
Solution
Riya starts at -0.7 m from the origin.
Step 1: She walks 3.3 m to the left. Since left is considered negative, we add -3.3 m to her initial position. So, -0.7 m (initial position) + -3.3 m (left movement) = -4 m.
Step 2: Then she walks 4 m to the right. Right is considered positive, so we add 4 m to her current position. So, -4 m (current position) + 4 m (right movement) = 0 m.
So, Riya's final position is 0 m from the origin.
