Answer:
15 cm
Explanation:
Displacement is the shortest distance between the point of origin of a body in motion to the final stopping positing.
For this ant's aunt's aunt that travels from the 15.00 cm mark to the 85.00 cm mark back to the 30.00 cm mark and then finally to the 30.00 cm mark, the displacement from the starting position is..
displacement = stopping point - starting point
d = 30 cm - 15 cm = 15 cm
