Distance and Displacement:
13. Chanice drives her scooter 7 kilometers north. She stops for lunch then drives 5
kilometers east. What distance did she cover?
What was her displacement?
14. Tara goes on a camel safari in Africa. She travels 5 kilometers north, then 3 km east,
and then another kilometer north. What distance did she cover?
What was her displacement (you may need to use a2+b2=c2).
Density:
