Answer:
0m
Explanation:
In physics this is 0m, why?
Okay so, you moved 60 meters (in position/m) the first 10 seconds (sec) and then between 10 and 15 seconds, you took a brake and didn't move. (The graph is still because the time is constant and your motion is 0 meters).
When 15 seconds have passed, you go back where you were, exactly at 0 meters, your initial position.
In reality would this be 60 meters + 60 meters back which would be 120 meters, or 0.12km if you will. But in physics world, it's 0 meters in position.
Hope you understood!
Good luck!
