Joey drives his car 7 km North. He stops for lunch and then drives 5 km south. What distance did he cover? What is his total displacement?

Respuesta :

ANSWER:

Distance: 12 kilometers

Displacement: 2 kilometers

STEP-BY-STEP EXPLANATION:

The first thing is to draw a picture of the situation, just like this:

The distance is the sum of the distances traveled, like this:

[tex]d=7+5=12[/tex]

The displacement is the vector sum, the distance from the starting point to the end point, therefore

[tex]D=7-5=2[/tex]

The distance is 12 kilometers and the displacement is 2 kilometers.
