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.
