Which distance can be most accurately measured with a ruler?

1

A person walks 1 mile every day for exercise, leaving her front porch at 9:00 AM and returning to her front porch at 9:25 AM. What is the total displacement of her daily walk?

1

A person drives north 3 blocks, then turns east and drives 3 blocks. The driver then turns south and drives 3 blocks. How could the driver have made the distance shorter while maintaining the same displacement?

1

A ball is rolled uphill a distance of 3 meters before it slows, stops, and begins to roll back. The ball rolls downhill 6 meters before coming to rest against a tree. What is the magnitude of the ball's displacement?

1

A girl walks from her home to a friend's home 3 kilometers north. She then walks east 2 km to the post office, 1 km north to the library, and 1 km east to the park. From the park, she walks 2 km west to the movie theater. After the movie, she walks 4 km south to the pet store.

a. What is the girl's displacement from her starting point to the pet store?
b. Calculate the distance she walked in kilometers.
