Question

Stephanie drives her electronic scooter 9km north. She stops for lunch and then drives 7km east. Whats the distance and displacement?

Answer 1

Answer:

distance=16km

displacement=11.4 km

Explanation:

As distance is the total length of the actual path .Therefore distance =(9+7)km=16 km

Now,displacement is the shortest path between initial And final positions

therefore,in this case,is given by using phythagoras theorem I.e.

$\sqrt{ {9}^{2} + {7}^{2} } = \sqrt{ 81 + 49} = \sqrt{130} = 11.4$

Hope it helps
