Distance vs. Displacement

An example of distance would be im "standing on a number line" im at (7) i walk 5 blocks more. The total length i traved was ( 7 + 5 = 12 blocks) 

An example of displacement would be my initial position is 0 i go to 6 then go back 3. The total displacement would be when i started at 0, i went 6 blocks.. Then went back 3 .. Which made me go back to 3.0 .

The difference between displacement & distance is that distance is saying how far you went .. Displacement ment your starting postion.. Then where you went next.. Then there.. Then you final position. The displacement would be more of the description on what you did(procedure to get to your number)
