Take the swimming pace of 100 meter as an example, the pace of 2 minutes and a half is between 2 minutes and 30 seconds and 3 minutes, which is the level that the public can generally reach. For swimmers, through certain training, improving swimming skills and physical fitness can further improve swimming speed. For beginners, it may take longer practice and guidance to reach the pace of 2.5 minutes.

It should be noted that swimming speed is only one aspect of evaluating swimming level, and other factors need to be considered comprehensively, such as technology, posture, breathing, strength and endurance. Therefore, both beginners and swimmers with a certain foundation should pay attention to all-round improvement in practice in order to achieve better swimming results.
