In an 800-meter training, Zhang Ming used 3. 15 minutes for the first time, 1 for the second time and 3 minutes and 03 seconds for the third time. Comparison, his place
To compare, these three times must be turned into the same number type. I'll convert it into decimals. 3 and 20 1=6 1/20=3.05, 3 seconds is equivalent to 3/60=0.05, so 3 minutes and 03 seconds =3.05. So to sum up, the second and third scores are the same, all of which are 3.05 points, just as good.
