Dora runs one lap around the track, finishing where she started. Clark runs a 100-meter dash along the straight side of the track.

Which runner traveled a greater distance?

Which runner had a greater change in position, start to finish?

See the answer below

Explanation:

Dora ran a complete lap around the track, including the straight side of the track; while Clark only ran a 100-meter along the straight side of the track.

Hence, Dora must have traveled a greater distance.

Dora finished the race where she started it, her change in position or displacement is zero. Clark finished the race at a different point from their starting position.

Hence, Clark a greater change in position than Dora.
