on his way to school,jed traveled 100 m north,300 m east,100 m north,100 m east,100 m north.
and the question is...
This reminds me of the cat that ate a piece of cheese, and then sat by the mouse hole with . . . baited breath!
The idea is that if the student did not even post the question, how much can we believe that he/she made any effort to solve the unstated problem?
To determine Jed's final position after his movements, you can visualize his journey on a coordinate plane. Let's start at the origin (0,0), with north being the positive y-axis and east being the positive x-axis.
1. Jed traveled 100 m north: His position changes from (0,0) to (0,100).
2. Jed traveled 300 m east: His position changes from (0,100) to (300,100).
3. Jed traveled 100 m north: His position changes from (300,100) to (300,200).
4. Jed traveled 100 m east: His position changes from (300,200) to (400,200).
5. Jed traveled 100 m north: His position changes from (400,200) to (400,300).
Therefore, Jed's final position is (400,300).
