Answer:
25 meters east
Step-by-step explanation:
Distance is the total amount of meters traveled by an object.
Displacement is how far away an object is from its original position at the end.
Pablo's original position is the science lab and Pablo's final position is at the chess club. Since you want to find the displacement, you want to find how far Pablo is from the science lab.
You find it by subtracting 35-10=25.
Since Pablo moved 10 m west, he was 10 m away from the lab. But, he moved 35 m east after. So, he went back the 10 m to the lab, plus the 25 m to reach the club, or a total of 35 m.
Very lengthy, but hope you understand!
