Final answer:
The distance traveled by the bicyclist is 0 km, distances traveled north and south cancel each other out.
Step-by-step explanation:
The distance traveled by the bicyclist can be found by calculating the total displacement in each direction. Let's break down the distances traveled:
- The cyclist rides 25 km east.
- Then, the cyclist rides 20.0 km west.
- Next, the cyclist rides 15 km south.
- Finally, the cyclist rides 15 km north.
To find the total distance traveled, we need to combine the distances traveled in each direction. When distances traveled east are added with distances traveled west, they cancel each other out since they are in opposite directions. Similarly, distances traveled north and south cancel each other out. Therefore, the total distance traveled is 0 km.
