Based on your description of the graph showing the progress of a student riding his bike, it sounds like there are segments of the graph indicating changes in speed (the zig-zags) and moments of rest.
Given that you can choose only two answers, the following statements seem most accurate based on the common interpretation of such graphs:
-
The student rode faster at the beginning, rested, then a little slower pace, rested, and then a little faster pace.
- This statement accounts for the zig-zags indicating changes in speed and rests.
-
The student stopped for at least one rest break.
- This statement is true as the presence of rest periods is implied with the zig-zag structure, indicating moments where the student was not progressing in distance.
So, the two best options are:
- The student rode faster at the beginning, rested, then a little slower pace, rested, and then a little faster pace.
- The student stopped for at least one rest break.
