A girl delivering newspapers covers her route by traveling 3 block west, 4 blocks north, and then 6 blocks east. What is her total displacement? Explain.
|dw:1327981777575:dw| You need to find AD
Apply pythagoras theorem and you get 5.
i kept getting displacement and distance missed up =0
explain: Displacement is the distance from it's final position to it's original position.
I got 7.81 using the pythagorean theorem.

Explain, please? Sorry
hmmm how do i explain ok the dotted line at the bottom right is 3 as the top side is 6 and the bottom left is 3 so you get 6-3=3. Now the vertical is same =4 so it is sqrt(3^2 + 4^2)=5
