aleksklad [387]

Answer:

Distance: 16m Displacement: 8m North

Explanation:

Total distance is the total amount traveled, regardless of direction. So, you would just add 12 and 4 to get a total distance of 16m. Displacement is the distance/direction from the start to the end point, regardless of which way you got there. So, to find displacement, you just subtract:

12m North - 4m South = 8m North
