This math topic focuses on comparing speeds of different entities across varied distance units and times. The main skills practiced include converting distance measurements and calculating speed to determine which entity moves faster. Specifically, the entities involved are bacteria and bugs, and the problems involve comparing their moving distances that are given in centimeters, meters, and millimeters against time frames of minutes, hours, and days. The emphasis is on understanding and applying concepts of speed in non-uniform units within practical contexts.
