This math topic covers problems on determining which among two subjects (bugs, horses, or bacteria) is faster based on given distances and times. The focus is on processing speeds with different units of measurement for time, such as minutes, seconds, and hours, challenging students to compare speeds under changed time units, which tests their ability to convert and manipulate time and distance measurements effectively. This set of problems is part of an advanced study on Speed, Distance, and Time.
