Chanices drives her scooter 7 kilometers north.She stops for lunch and then drives 5 kilometers east.What distance did she cover?What was her displacement
Distance covered was 12km, 7km then another 5 so just 7+5. As there is a right angle, we can use Pythagoras’ theorem to figure out the displacement. This would be x^2 = 7^2 + 5^2, so x=8.6km
