Question

7. My little sister wants to ride her tricycle. She jumps on and heads east for 1000 m before sheturns around and comes back to the west for 300 m before falling off. What is the distance mysister traveled? What is my sister's displacement?NES

Answer 1

First let's make the picture of the movement of the little sister:

The green line represents the first trip and the red line represents the trip back.

Since she traveled 1000m and then came back 300m, we have that:

$1000m+300m=1300m$

therefore, the little sister displaced 700 meters and she traveled 1300m
