According to the description of the question, Chen Bing, Wang Hong, and Zhang Ye were taking a walk on a 560-meter circular track. We can use these numbers to make deductions and calculations. Chen Bing walked 80 meters per minute, so he walked 560/60=8 minutes. Zhang Ye walked 70 meters per minute, so he walked 560/60=9 minutes. Wang Hong walked 88 meters per minute, so he walked 560/60=95 minutes. Since the three students were walking 80 or 90 meters per minute, it could be inferred that their speed should be (80+90+88)/60=18 meters per minute. Therefore, Chen Bing, Wang Hong, and Zhang Ye's speed should be 18 m/min, which is 18 x 6 = 108 m on the circular track.
