Three runners start at the same place. Shaun runs 4.0 km due east and then runs 1.0 km due west. Mark runs 3.0 km due east. Jeff runs 2.0 km due west and then runs 5.0 km due east. Which of the following is true concerning the displacement of each runner?

1. Shaun's displacement equals Mark's displacement, but Jeff's displacement is different.
2. Shaun, Mark, and Jeff have different displacements
3. Shaun's displacement equals Jeff's displacement, but Mark's displacement is different
4. Mark's displacement equals Jeff's displacement, but Shaun's displacement is different Shaun, Mark, and Jeff have the same displacements

Three runners start at the same place. Shaun runs 4.0 km due east and then runs 1.0 km due west. Mark runs 3.0 km due east. Jeff runs 2.0 km due west and then runs 5.0 km due east the,

Shaun, Mark, and Jeff have the same displacements. DISPLACEMENT IS NOTHING BUT SHORTEST DISTANCE BETWEEN THE INITIAL AND THE FINAL POSITION OF THE OBJECT.

Hence correct answer is 4
