Lily and Ella Physics: Position, Velocity, and Acceleration

Ella starts at her house and travels 15 meters in the positive direction before realizing she forgot her favorite toy. She goes home and gets her toy, then reaches her destination location 35 meters in the positive direction from the house

What is Ella's total displacement?

Ella starts at her house and travels 35 meters before realizing she forgot her favorite toy. She goes home and gets her toy, then reaches her previous location 35 meters from the house

What is the total distance that Ella traveled?
